An accused in India's infamous mob lynching case has died at a hospital in capital New Delhi.

The 20-year-old accused Ravi Sisodia died on Tuesday due to kidney and respiratory failure after he was taken to the hospital two days ago after he complained of some pain.

However, his family alleges foul play and said that their son died due to atrocities of police officials inside the prison. He was one of the 18 accused in the Dadri lynching case.

On Sep. 28 last year, just after the Muslim festival Eid-al-Adha, attackers killed 52-year-old Mohammad Akhlaq Saifi and seriously injured his son Danish.

Hindu fringe attacked them over suspicion that the two have eaten beef in country's Northern Province of Uttar Pradesh's Dadri.

The incident created an uproar and led to the mass protest across the country triggering the debate rising intolerance towards minority Muslim community in India.

The right-wing mob had broken into victim's family home and beat him to death by dragging his body out into the street of Bisara village in Dadri.

Eating beef is considered a taboo in Hindu majority India, who comprise more than 80 percent of the country's 1.25 billion people.

India's majority Hindu community see cows as holy. But beef is widely eaten by Hindus in some parts of the country as well as by members of lower castes and minority Muslims and Christians.

The anti-beef movement, which is going on from last year in India, promulgates an ideology of right wind Hindu organisations that sees India as Hindu nation.

India is the world's largest exporter of beef and its fifth biggest consumer but its ruling right wing Bharatiya Janata Party (BJP) led by Prime Minister Narendra Modi wants a nationwide ban on cow slaughter and the beef trade, which is run mostly by Muslims.
