A sex attacker has been banned from the London Underground and DLR network after admitting to flashing and rubbing himself against women on the Tube.

Malcolm Schwartz, of Kingsground in Eltham, was spared jailed and received a 62 week suspended prison sentence at Blackfriars Crown Court on Monday.

The 19-year-old sex pest committed four sexual assaults on London Underground services between December and January this year.

The first offence happened on board a busy Central Line train between Mile End and Bethnal Green at approximately 8.30am on December 14.

Schwartz’s boarded the service and approached a 26-year-old woman where he then exposed himself, pressing himself against his victim.

The following month, on January 8, Schwarts targeted two women in the same morning. During each assault, he once again pressed himself against his victims.

The forth incident took place at Bethnal Green station, where Schwartz stood behind his victim, touching her inappropriately as the train traveled.

Schwartz has been banned from traveling on the London Underground, DLR, and from sitting next to a lone woman he does not know.

His name will also be listed on the sex offenders register for ten years.

DC Thomas O’Regan from the Sexual Offences Unit of British Transport Police, said: “Schwartz’s behaviour was perverse.

"Over a two month period of time, he travelled on busy Central Line trains assaulting women for his own sexual gratification.

"His conduct was outrageous and I am pleased we were able to catch him.

“This complex case demonstrates the true value in reporting unwanted sexual behaviour to police.

"The victims each provided us with clear accounts of what happened, enabling us to clearly identify Schwartz as the perpetrator.

"Reports such as theirs help us catch offenders, and ensure that justice is delivered.

“I hope today’s sentence sends a very strong message that sexual assault on the transport network will not be tolerated.

"Everyone should be free to travel without a man like Schwartz targeting them.”
