A PAEDOPHILE cop was jailed for two-and-a-half years yesterday after being caught when a colleague posed online as a girl aged 12.

Married David Geering, 48, had been a detective with the Metropolitan Polices Homicide and Serious Crime Command.

But all the time he was a child sex pervert trading hundreds of vile images with other sickos.

A number of photos featured the most extreme kind of child abuse.

Geering was found to have taken indecent photos of two kids himself.

He used the false name Nigel Robotham to cover his tracks but was nabbed when he made internet contact with someone he thought was a 12-year-old girl.

It was actually a fake identity assumed by officers from the Met Police Paedophile Unit.

Three of his computers were traced to an internet cafe in Londons Victoria district, an address in Hertfordshire and a property in Spain.

Checks with other forces revealed Geerings evil trade in images of kids.

Geering was jailed at Londons Southwark Crown Court on 20 counts of distributing indecent images of children and two counts of taking indecent images of children.

The cop of 27 years was convicted last month.

Det Supt Sue Knight of the Mets Child Abuse Investigation Command said: It is a reminder to paedophiles that wherever they go and whatever their occupation, the Met will track them down.
