A man has been jailed after attempting to sexually assault two children. 

Alfred Dempster, 57, tried to lure two people he believed were children into sexual activity.

He began talking to someone he believed to be an 11-year-old girl on KIK Messenger - a popular messaging platform with youngsters -  before moving to Whatsapp on New Year’s Day 2020.

Dempster, who was actually speaking with a member of an online child activist group, asked them to send an explicit photo, touch themselves and call him "daddy". 

The contact ended on January 9, 2020. 

Dempster also began speaking to another decoy pretending to be a 14-year-old girl in November of the same year.  

He asked for photos, said he wanted to have sex and also encouraged them to touch themselves.

Dempster was arrested at his home in Nene Quay, Wisbech, on January 11, 2021, and his electronic devices were seized.

He was jailed for two years and six months on February 2 at Peterborough Crown Court after pleading guilty to two counts of attempting to incite a girl to engage in sexual activity. 

Two counts of attempting to engage in sexual communication with a child, which Dempster denied, were ordered to lie on file. 

DC Zip Lloyd said: “This was a disgusting case where Dempster showed intent to potentially sexually assault two children.”
