A gang of robbers allegedly murdered a paan shop owner who foiled a robbery they were planning to carry out at Ghatkopar, thrashed them up and then poked fun at them for their failed attempt.
The deceased, Chand Sayyed, 30, was found with his throat slit on the tracks near Ghatkopar railway station in the early hours of Wednesday.
The Kurla government railway police (GRP) have arrested three persons involved in the murder.
The accused have been identified as Nasir Shaikh, Amar Sahu and Binu. While Shaikh is aged 19, Sahu and Binu are in their early twenties.
The fourth accused, who is yet to be identified, is currently absconding.
The murder came to light when the police caught Shaikh, who was wanted for stealing mobile phones.
During interrogation, Shaikh confessed to the murder and named his three accomplices, said a Kurla GRP officer on condition of anonymity, as he is not authorised to speak to the media.
Sayyed had come to the city around eight days ago from Kolkata to find a job. He was residing with his brother Latif Shaikh at Nityanand Nagar in Ghatkopar (West).
A few days back, Sayyed had set up a paan shop near the Hanuman temple in Nityanand Nagar.
According to the police, on Tuesday, the accused had come to Nityanand Nagar to carry out a robbery. However, they were caught red-handed by the locals.
They were then thrashed by Sayyed and other residents, following which, they fled the spot.
The accused told the police that they were incensed after Sayyed made fun of them and they decided to teach him a lesson.
On Wednesday morning, the quadruplet dragged Sayyed out of his shop, took him to the railway tracks near Ghatkopar station and slit his throat.
