A male model and teaching assistant who campaigned against knife crime was stabbed to death after robbers used Gumtree to lure him into a trap to steal his laptop.

Michael Adegbite, who also worked as a fitness instructor and football coach, was attacked after he advertised his secondhand MacBook on the popular classifieds website for £200.

He and a friend went to meet someone they believed was a buyer in Enfield on Sunday evening but were confronted by three youths. Detectives believe the men lured the 28-year-old to the rendezvous with the intention of mugging him for the laptop. Mr Adegbite and his friend managed to snatch the laptop back and the suspects ran off.

Police say that a short time later, a second friend joined the victim and the three men set out to look for the group who had attempted to rob them. Minutes later there was a confrontation and a scuffle in the street and Mr Adegbite was stabbed once in the chest. He died at the roadside 30 minutes later despite frantic attempts by neighbours and paramedics to save his life.

Three 18-year-old men have now been arrested in connection with the incident and are currently being questioned by police.
