New Delhi: Police cracking a bizarre case of a man seeking revenge on the relative of a girl he had sought to marry, used his minor sister as bait to honey-trap the relative. The relative apparently who had opposed the alliance was brutally killed.

The sinister plot unfolded as per the man's plan. His sister befriended the target and called him to a "romantic meeting" at Tughlakabad Fort in southeast Delhi. The target walked right into the trap.

In the ruins of the fort, the accused and his DJ friend allegedly stabbed the victim repeatedly, then poured kerosene on the body and tried to burn it. Cops stumbled upon the body a few days ago. The victim was identified through a tattoo on his hand, but police initially got no leads on the murderer(s).

However, technical surveillance and the statement of a friend of the victim - who had accompanied the victim but had fled suspecting foul play - enabled the cops to solve the case within 96 hours.

On Friday, DCP (south east) Chinmoy Biswal said that the accused man, his sister and her juvenile woman friend, the DJ and two other friends have been arrested. Identity of the accused is withheld as minor girls were allegedly involved in the crime. The main accused made a living by preparing legal documentation.

On May 6, a partially burnt body with multiple stab injuries and a slit neck was found at the Tughlakabad jungle adjoining the mediaeval fort. The body had no source of identification on it, except a tattoo on the forearm.

Enquiries were conducted in nearby areas for a missing man with a tattoo. This led to the victim's identification as Neeraj from Faridabad. During investigation, it was found that Neeraj was in a relationship with a minor girl for the past 15 days and that the girl who had called him up that day. The cops found the number of another girl active at the scene of crime and interviewed her. She confessed to the crime and spilled the beans on her friend. The two girls led the cops to the girl's brother and his friends. During interrogation, the accused revealed the plot.
