The victim, identified as Abhishek, was returning home at 1 a.m., when he met with the freak accident on a West Delhi road where the wire was tied between the barricades by the beat constables.
The police said the deceased worked as a private cab driver and was returning to his Netaji Subhash Place residence.
"When he reached near the Subhash Place police station, he was passing through four police barricades.
"His neck got stuck in the wire that was tied between two of the barricades. He died on the spot," Deputy Commissioner of Police Aslam Khan said.
"Initial investigation pointed to negligence of the area Station House Officer, four Constables, a Head Constable and a Sub-Inspector and an Assistant Sub-Inspector from the division staff. We have sent SHO Arvind Kumar to the district police lines.
"Head Constable Jitender, and Constables Balkari, Ravinder, Mukesh and Gaurav, and division officers -- SI Sandeep Dabbas and ASI Ravinder -- have been suspended for negligence in duty. A case has been registered against them and a probe is underway," the officer said.
It has been found that during the night, beat constables on night duty barricade roads and locked them with iron chains instead of staying up on vigil.
