Barnardo’s, the children’s charity, has warned hoteliers and bar staff near to the Olympic Park in Stratford to be on the lookout for any vulnerable youngsters during the Games.

The organisation has produced an online leaflet to help those in the travel and hospitality industry spot the signs of sexual exploitation.

And it has called for better data collection of the crime to prevent children being abused during the event.

Chief executive Anne Marie Carrie said: “With a huge influx of visitors to the capital everyone needs to play their part in spotting the signs that sexual exploitation is taking place.

“We must pull together to ensure that protection of vulnerable children is gold standard during the Olympics.”
