Taxi drivers, hotel staff and those working at fast food outlets have taken part in a training day to help combat child exploitation.
Police officers investigating the issue in the county have organised the training in Huntingdon as it is believed people working in these areas may witness key behaviour.
Some perpetrators use taxis to transport children to locations, often hotels, to be exploited. The offenders may regularly buy the victims gifts, or take them to fast food outlets as part of attempts to groom them.
In addition to representatives from local businesses, staff from nearby branches of McDonald's will be attending the day help workers identify when someone may be at risk of exploitation.
Both girls and boys can become victims of exploitation - with people they see friends or boyfriends taking advantage of them sexually or by coercing them into committing crime such as selling drugs.
