A sex offender who assaulted women on crowded trains has been jailed.

Lloyd Weekes, 52, of Holly Park Estate, Finsbury Park, London, molested four women during rush-hour on Northern and Central Line trains between December 2011 and March 2013.

Mr Weekes, who pleaded guilty to the charges of sexual assault at Blackfriars Crown Court, first attacked a woman on a Northern Line train between Clapham Common and Stockwell at 8.35am on December 1, 2011.

A woman was making her way to work on a busy train when she noticed Weekes was standing unusually close to her.

He touched her for several minutes before she shouted at him, causing him to leave the train at Stockwell station.

The second incident took place on the Central Line between Holborn and Chancery Lane at 5.30pm on February 14, 2013.

Again, Weekes stood next to, and repeatedly touched, a woman on the crowded train as she attempted to make her way home from work, before getting off at Chancery Lane.

On Friday, February 22, at 5.30pm, Weekes was on a Central Line train on the same route, standing too close to a woman as she travelled on the train and touching her inappropriately.

Weekes was caught on March 7 when officers spotted him attempting to inappropriately touch a woman as he travelled on the Central Line.

Weekes was sentenced to four years in jail and put on the sex offenders' register for five years.

Sergeant Anna Fisk, from BTP’s Public Protection Unit, said: “Without the help and co-operation of each of the victims in these cases, this successful prosecution would not have been possible.

“I would like to take this opportunity to praise and thank each of them for their help and cooperation in what were hugely distressing and upsetting situations for them.

“No one has the right to make people feel vulnerable as they travel on the rail network, as Weekes did on numerous occasions.

“This kind of unwanted sexual behaviour is exactly the kind of conduct we are committed to identifying and stamping out.

“I would encourage anyone who feels they have been a victim of anything similar to follow the example set by Weekes’ victims by reporting what happened to us.

“This can help us deal with the person responsible, and can help stop it happening to someone else.”
