A man who forced a stranger to give him a lift at knifepoint has been locked up indefinitely for the protect-ion of the public.

David Hill was sitting in his car in a car park in London Road South, Lowestoft when Mark Peacock, who was holding a knife, opened the driver's door and told him: "You are going to drive me, or I'm going to stick this in your throat," Ipswich Crown Court heard.

Peacock got into Mr Hill's car, said prosecutor Andrew Shaw and told Mr Hill to drive him to Diss, Banham and finally to Quidenham.

Mr Shaw said Peacock reassured Mr Hill he was not going to hurt him, but said people were trying to kill him. Later that evening a resident of Quidenham saw Peacock standing on the roof of his shed.

Peacock was arrested on suspicion of kidnapping Mr Hill, and a small knife was found on the shed roof.

Peacock, 32, of Harold Hill, Essex, admitted false imprisonment and poss-essing an offensive weapon.

Judge John Devaux said he felt there was a significant risk to the public of serious harm caused by Peacock committing further offences.

He passed an indeterminate sentence but said Peacock would serve a minimum of two-and-a-half-years.

Ayshia Khan, for Peacock, said her client had been hearing voices in his head.
