A vile man who preyed on a vulnerable teenage boy who had run away from home to have sex with him has been jailed.

Daniel McKenzie, of Victoria Road, Tottenham, offered the 13-year-old a place to stay after he spotted him asleep on a train.

The child agreed and when they got to McKenzie's house, they started smoking cannabis before having penetrative sex.

But the boy, who had been reported missing, then left and tried to make his way home - but got lost and ended up at Edmonton Police Station.

It was not until officers took him home that he finally admitted what happened and an investigation was launched.

Sick McKenzie was arrested by police or possession of cannabis and theft from a motor vehicle.

Before he was bailed, his DNA was taken and police were able to link him to his sexual crime.

McKenzie was sentenced after pleading guilty to one count of sexual activity with a child under 16 and placed on the sex ofenders' register for life.

He will get four years and ten months behind bars.

He was also given a ten-year Sexual Harm Prevention Order.

Detective Constable James Taylor from the Sexual Offences, Exploitation and Child Abuse (SOECA) Command led the investigation - he said: "I truly hope McKenzie's imprisonment will help the victim and his family towards closure and also send a message out to offenders that we will do our utmost to find you, arrest you and convict you.

"I would also like to thank the support services and partner agencies for working together during this difficult case."

Detective Sergeant Edward Coleman of SOECA who supervised the investigation said: "As is often the case, not all victims recognize that they are being preyed upon.

"This young person was preyed upon by Daniel McKenzie at a time when he was most vulnerable and has been extremely brave in coming forward to give evidence.

"Such abuse and exploitation of children will not be tolerated by the Metropolitan Police Service and we are determined to bring all such perpetrators to justice. If you believe a child you know may be being exploited in this way, please call police."
