Police in Jakarta have arrested a man who admitted to playing a Japanese adult video on a giant electronic billboard at a busy street, a spokesman said Wednesday. 

Motorists were shocked last week when the LED screen reserved for advertising in South Jakarta displayed scenes showing two people having sex for about five minutes before power to the display was abruptly cut.

The 24-year-old man had hacked into the computer system belonging to the company that operates the billboard and streamed the video from the internet, Jakarta police spokesman Awi Setiyono said.

“He’s got tech skills and too much time on his hands,” Setiyono said, adding that the suspect works for an information technology company.

He could face a maximum sentence of six years in jail if found guilty of violating the country’s tough information technology laws, he said.
