A 34-year old man was hacked to death allegedly by a three-member gang in Athani near Aluva on Sunday night, police said.
Police identified the deceased as Binoy.
Gang rivalry is said to be the reason for the murder, police said.
A CCTV visual collected from a nearby building has captured the incident.
The visuals aired by local television channels on Monday showed Binoy being attacked using deadly sharp-edged weapons in front of people by the gang on the highway at around 8 p.m on Sunday.
Binoy is accused in many criminal cases, police said.
Police said a hunt has been launched to nab the accused.
