BISARA: The murder by a Hindu mob of a Muslim man rumoured to have slaughtered a cow has thrown a spotlight on the hardline, polarising agenda of some followers of Indian Prime Minster Narendra Modi, undermining his promise of development for all.

On a tour of Silicon Valley last month where he was feted by United States (US) tech gurus and Indian émigrés, Modi won a pledge from Microsoft to provide low-cost Internet for 500,000 villages to back his vision of a globally networked "Digital India."

One such village is Bisara, 50 kilometre from the capital New Delhi, where a crowd of assailants broke into 50-year-old Mohammed Akhlaq's home last Monday night, beat him to death and severely injured his 22-year-old son Danish.

The local member of parliament, Mahesh Sharma, is also Modi's culture minister and has hit the headlines of late with statements that show a different side to their ruling Hindu nationalist party. In one recent speech, Sharma vowed to cleanse public life "polluted" by Western influences.

Visiting Bisara this week to pay his respects to Akhlaq's family, Sharma said the killing could have been an "accident."

"How can the leader call my husband's murder an accident?" said Akhlaq's widow Ikraman, who suffered facial injuries, speaking to Reuters at the family home. "I don't think the minister knows the difference between an accident and murder."

Critics say Sharma's comment implicitly condoned Akhlaq's lynching and pandered to fringe Hindu militants who have recently become active in the district.

Eating beef is a taboo for many Hindus, who make up 80 per cent of India's population of 1.25 billion people, but not for the country's 175 million Muslims.

Many Hindus regard the cow as the living symbol of their religion and being sacred.

Blood on the walls

Communal clashes had never erupted in Bisara, home to 400 landowning Hindu and 35 Muslim families, even when religious riots have broken out in the region.

In 2013, 65 people died in sectarian strife around the northern town of Muzaffarnagar.

But an announcement by a Hindu priest over his temple loudspeakers that Akhlaq had butchered a cow and that his wife was cooking beef for dinner brought a sudden end to the village's tradition of tolerance, according to family members and villagers who heard the call.

Within minutes a mob stormed into Akhlaq's house, vandalised the kitchen in search of beef and beat the 56-year-old blacksmith to death with bricks and stones. His body was dragged out in front of his family.

Akhlaq's youngest son, who suffered severe head injuries, is fighting for his life in a hospital intensive care unit after undergoing two brain operations.

His widow says he was killed for a crime he did not commit.

"Even now I can't believe that my Hindu neighbours killed my husband. My neighbours were like my extended family," said Ikraman, who will spend a month in mourning in a room near the bloodstained murder scene.

Premeditated attack?

Local Muslims say Akhlaq's killing was a pre-meditated attack aimed at polarising the village on religious lines by militant Hindu groups loyal to Modi's Bharatiya Janata Party (BJP), which rose to power in the May 2014 general election.

Sharma and Modi are both members of an umbrella group, the Rashtriya Swayamsevak Sangh (RSS), that is the BJP's ideological parent. The movement propagates an ideology of Hindutva, or Hindu-ness, which asserts that India is a Hindu nation.

Police have arrested seven Hindu youths over the murder and one paramilitary soldier accused of planning the attack.

The main accused Vishal Rana, 20, and seven others belong to the Rana family who are known to be affiliated with the BJP. Sanay Rana, father of the accused, is a local BJP leader.

Vishal allegedly organised the meeting in which the mob was incited to attack the Akhlaq family for wrongfully consuming beef.

Vishal stopped studying after class 12, reportedly because he was unwell, and now works at his brother-in-law's advertising agency in South Delhi.

Brothers Vivek, 22 and Sachin, 20 are also related to Rana, who help their father Om Kumar with his electricity appliances repair business.

Four others accused, Saurabh, 21, Gaurav, 22, Shivam,19 and Sandeep,18 were also part of the violent mob.

Investigators are also searching for Hindu activists who spread rumours and online posts stating that Akhlaq had stored 6 kilogramme of beef in his refrigerator.

The region holds village council elections next week and Bisara has, in the wake of the killing, become a magnet for campaigning politicians.

One BJP lawmaker accused of instigating the Muzaffarnagar riots came to Bisara on Sunday and warned of a "befitting reply" if the suspects were prosecuted, according to news reports.

Many Indian states, including the country's largest Uttar Pradesh (UP), where Bisara is situated, have banned cow slaughter for more than two decades.

Modi's party has, in states where it rules, clamped down further on eating beef — even though India is the second largest exporter and fifth biggest consumer in the world.

In recent months, government leaders have advocated a national ban on cow slaughter.

Beef vigilantes

Critics say tougher anti-beef laws discriminate against Muslims, Christians and lower-caste Hindus who rely on the cheap meat for protein.

The crackdown has, meanwhile, provided cover for the rise of Hindu vigilante groups.

Such groups attack cattle trucks, track religious conversions in villages and towns, and warn Hindu girls against falling in love with Muslim boys. Modi has expressed no disapproval towards them.

"Those who spread this poison enjoy his (Modi's) patronage," political analyst Pratap Bhanu Mehta wrote in the Indian Express.

"This government has set a tone that is threatening, mean-spirited and inimical to freedom."

Sharma's office said the minister was demanding an independent federal investigation into Akhlaq's murder.

Calls on Sunday to three officials in Modi's office went unanswered.

At least 16 men from Bisara joined a new militant Hindu outfit called the Samadhan Sena (Solution Army) in August.

The group is not formally tied to the RSS but two members told Reuters they would enforce its agenda in every village.

"Akhlaq should not have butchered a cow," said Ajay Singh, a member of the Samadhan Sena in Bisara. "He should not have forgotten that India belongs to Hindus first."
