A young man with Asperger's syndrome was attacked by 'teenagers' on mopeds as he walked home in Worcester Park.

The 22-year-old was grabbed by the hair and pulled to the floor by thugs yesterday (July 27)

His mum told Sutton Guardian: “He was walking from the shops back to our estate where we live and the mopeds came round the roundabout and grabbed him by the hair and pulled him to the floor and drove off.”

She said her son arrived home in Manor Drive by 5.45 pm.

She added: “He is fine but his head was really sore where they grabbed his hair.".

According to the mum, her son said that the incident involved two mopeds and three “quite young teenagers” who stayed on the moving mopeds as they grabbed him to the floor.

The mother continued: “They are going for vulnerable people. They are not confronting anyone. Cowards.”

The mum and son decided to report this to the police after hearing of another attack in the same area that evening.

The other incident allegedly involved two mopeds and occurred at 5.25 pm.

An anonymous post on social media claimed a “sexual assault” by "three lads around 16 to 17 years old on their mopeds at the lights on the Malden road, junction Sheephouse way. [South Lane] Opposite Manor park".

The poster wrote: "I was waiting at the lights on my push bike and they drove up behind me and grabbed me all over my upper half. I said how dare they touch me and they then started shouting at me, lots of names and lots of bad language. I was so scared that they were going to hit me. They then drove off down Sheephouse way.

"I have reported it to the police. I was just so shocked. I would be really nervous what they may try to do next so thought it best to share."

Police told Sutton Guardian that they would be speaking to a victim of a sexual assault today.
