An abusive message was displayed on a digital traffic advisory board in Dindoshi area of Mumbai following which a case was registered against unidentified hackers, a police official said.
The city civic body had installed smart traffic poles near a mall in Goregaon (east) suburb. A contractor had placed two LED screen boards on one of the poles for displaying traffic-related advisories.
At 9.10 pm on Thursday, an abusive message was displayed on the LED screen, the official said on Monday.
The message remained there for more than an hour before the power supply to the board was cut off, he said.
The contractor who had installed the boards told civic officials he was not aware of the incident.
He told the police that somebody might have hacked into the system and relayed the message.
A case was registered against unidentified hackers under related sections of the Indian Penal Code and the Information Technology Act, the police official said.
