Cinemas, dvd rental firms and computer game sellers have agreed to beef up their checks on the age of teenagers who want to borrow or watch films or play violent computer games.

Cinema and shop owners signed an agreement on Wednesday pledging to be stricter in the way they apply recommended age limits on films and games.
Research by Twente University showed 11-year-olds attempting to buy a film or game with a 16 plus classification are only stopped 31% of the time. And 15-year-olds are able to buy or rent the film 96% of the time, the research showed.
