- Junaid Khan, 16, was killed by mob on a train last week
- 4 men arrested today for instigating the mob to kill him
- Man who stabbed him to death still not caught
Also, a man filmed by security cameras at a community centre near where Junaid Khan was thrown off the train has been identified as the man who likely stabbed the teen who bled to death. He has not yet been found.
Police say that another Delhi government employee who yelled "beef-eater" and "anti-national" at Junaid Khan, his brother and their two cousins has been identified but not arrested.
One man, identified only as Ramesh, was arrested by the Haryana police over the weekend.
The mob that attacked Junaid Khan, 16, and his three companions including his brother Haseeb, accused them of carrying beef in their bags and was made up of about 20 people, relatives have said. The attack took place on a train running between Delhi and Mathura.
Police officials say that despite the train being packed with commuters, no witnesses have come forward, making it much harder to identify and arrest the killers.
The lynching of Junaid Khan triggered national protests on Wednesday - in different cities, people marched as part of a campaign called "'Not In My Name" to call for an end to the recent spate of mob attacks, some of which have been undertaken by self-declared cow vigilantes who accused the victims of carrying or eating beef.
Junaid Khan was traveling home from Delhi to his village of Ballabhgarh in Haryana on Thursday with his brother and two cousins when the mob turned on them.
Law Minister Ravi Shankar Prasad has described Junaid Khan's killing as "extremely painful and shameful" and said the government will not tolerate such attacks.
