AN Ipswich teenager is behind bars today after threatening to knife a police officer and put him in a coffin.

Kerron Turner, of Ancaster Road, was sentenced to 16 weeks in a young offenders' institution when he appeared before South East Suffolk Magistrates Court in Ipswich.

The 18-year-old had pleaded guilty at an earlier hearing to assaulting the police officer and disorderly behaviour in the town centre.

At his sentencing, the court heard Turner had been drinking in Ipswich during the evening of Saturday, April 4.

The teenager was drunk when he was thrown out of Edwards public house in Great Colman Street by staff.

Instead of leaving the area, Turner attempted to get back into the premises, but was prevented from doing so.

Police intervened and tried to calm the situation down.

However, Turner continued to be unruly and was arrested for disorderly behaviour by Pc Ian Rafferty at around 10.20pm.

The officer put him in the back of a police van, where Turner lashed out at the police constable and hurled a volley of abuse at him.

Magistrates heard that at one point the teenager kicked Pc Rafferty, before lifting his knee violently into the police officer's groin.

Turner continued to swear and be abusive as he was being taken to Ipswich police station where he was also charged with assaulting a police officer.

Prosecutor Andrea Reynolds told the court that at one point Turner told Pc Rafferty: “You won't be laughing when I knife you and put you in a coffin.”

Magistrates sentenced Turner to 16 weeks' detention for the assault on the police officer. No separate penalty was given to him for the disorderly behaviour offence.
