A pervert who showed two primary schoolchildren pornography on his mobile phone was behind bars this week.

Leon Harris, 26, approached the youngsters, aged seven and nine, while they were with their mother in the arrivals hall at Heathrow Terminal 4, before he suddenly pulled out his phone and played the graphic video.

Their shocked mum stepped in, but Harris then turned and showed her the clip. The woman called for security and two baggage handlers rushed to help.

Police arrested Harris and charged him the following day on January 18 this year.

It led to unemployed Harris, of no fixed address, facing trial at Isleworth Crown Court where he was found guilty on May 20 of showing pornography to children under the age of 13 for the purpose of sexual gratification.

He was remanded in custody and is due to be sentenced on July 10.
