Revealed: Video that nailed pervert who molested schoolgirl (14) on Dublin bus

Footage of the data engineer carrying out the sexual assault on the teenager was posted online in the wake of the incident in an effort to identify the pervert.

It shows how Balasubramaniam used his bag to cover his hand as he molested the teenager.

He can then be seen getting up and covering his head with the hood of his coat before going down the stairs of the double decker bus.

Last week Balasubramaniam was given a suspended sentence for the assault which the court heard occurred after he sat down next to the teenager who was sitting alone on a Dublin bus.

Balasubramaniam (27) sat beside the victim and concealed his hand with a bag before rubbing her leg and trying to put his hand up her skirt, a court had heard.

Judge David McHugh imposed a four-month sentence which he suspended for two years.

The accused, with an address in west Dublin, had previously pleaded guilty to sexual assault.

Garda James Byrne previously told Blanchardstown District Court that the girl was travelling home on a bus from the city centre on the afternoon of April 26 this year when a “lone male” got on and sat next to her. He was unknown to her, the court heard.

Balasubramaniam placed his right hand on the girl’s left thigh and he rubbed her leg with his thumb, under her school skirt.

The girl believed this to be intentional and told her family when she went home. She and her mother went to a garda station and reported she had been touched inappropriately.

The victim later told a specialist garda interviewer that the defendant had placed a bag on his lap which covered his hand and she felt movement on her leg.

His whole hand was there but she felt his finger rubbing and she said he tried to put his hand up her skirt above the knee.

She gave gardai a description of the accused, who was later identified and charged.

The court previously heard Balasubramaniam was originally from India. He was a data app engineer and was married. He had since lost his job.

The Judge McHugh was told the victim wished to forget about the incident and move on with her life.
