A MOPED gang tried to rob a mother as she walked down a street with her three-year-old daughter.

Footage of the attack was shared by TV star Amanda Holden, and shows the thugs threatening the woman before being chased off by workmen, one of whom was wielding a scaffolding pole.

The Britain’s Got Talent judge, yesterday urged her 2million Twitter followers to identify the ‘scumbags’ behind the attack.

CCTV shows four men, all dressed in black, pull up on a black moped and a motorbike. Two men get off and wait for someone to rob.

When the unknown woman walks past, the men confront her and appear to reach for the child as they demand valuables. The mother picks up her daughter and runs into the road, prompting a scaffolders’ truck to stop.

The muggers walk off empty-handed, pursued seconds later by three workmen. The incident happened in Petersham, south-west London at 12.35pm last Thursday, said the Met Police.

‘A woman was approached by men who demanded her jewellery,’ a Scotland Yard spokesman said.

‘They threatened her and a child who was with her. No injuries were reported No weapon was seen, although it was intimated.’

No arrests have been made, he added.

Posting a video of the incident, which happened close to her home in Richmond, Holden, 47, wrote: ‘So this I know is happening everywhere but this was in broad daylight. Mother and child attacked. And some heroes in a lorry chased them off. Call 101 if u know these scumbags.’

Met Police figures show crimes committed using mopeds, scooters and motorcycles soared by 50 per cent in the year to May, to 22,025. That is the equivalent of 430 raids a week. Some thieves claim to earn £2,000 a day.

■ TWO moped muggers who pulled a gun on a teenage victim are on the run from police. The robber who waved the gun ordered the 17-year-old boy to hand over his necklace in an attack in Beckenham, south London, at 2.15pm on Sunday. In the same incident, a man aged 58 was dragged into a road by the thieves who snatched a necklace he was wearing. About 45 minutes earlier, two men aged 26 and 32 were attacked in a car park in Lewisham. One of the victims had a ring and watch stolen. The muggers in both attacks wore black helmets, tracksuits and gloves.
