An advertising campaign showing a woman's breasts has been blamed for more than 500 traffic accidents in one day.

The massive adverts placed on the side of 30 trucks driving around Moscow showed a woman's breasts cupped in her hands with the slogan 'They Attract' across her nipples.

As the trucks trundled around the streets of the Russian capital, they left a trail of carnage as male drivers became so distracted they ploughed straight into each other.

A total of 517 accidents were reported.

The stunt, by an advertising agency specialising in mobile adverts, backfired after police sent out patrols to round up all the vehicles and impound them until the risque images could be removed.

Motorist Ildar Yuriev, 35, said: 'I was on my way to a business meeting when I saw this truck with a huge photo of breasts on its side go by.

'Then I was hit by the car behind who said he had been distracted by the truck. It made me late and left my car in the garage, and although I am insured I am still out of pocket.'

Furious drivers across Moscow have reportedly bombarded the agency with compensation claims.

A spokesman for AdvTruck.ru, which ran the promotion said: 'We are planning to bring a new advertising format onto the market, encouraging companies to place their ads on the sides of trucks, as we thought this would be a good alternative to putting them on the sides of public transport.

'We wanted to draw attention to this new format with this campaign' he explained.
