Britain: The Nigerian immigrant accused of murdering PC Jon Henry has been remanded in custody
Ikechukwu Tennyson Obih appeared in court charged with stabbing to death the 36-yearold father of one.
The Nigerian, who arrived in the UK in 2000 and was later granted indefinite leave to remain, was handcuffed to a prison guard and flanked by three policemen.
The 27-year-old was also charged with the attempted murders of window cleaners Steven Chamberlain and David Knight.
He faces a fourth charge - related to a separate incident on Monday - of armed burglary.
Obih, who was wearing a blue jumper and light trousers and had a large plaster over his left eye, was ordered to remove his hand from his pocket by the clerk of Luton Magistrates' Court as he stood in the dock.
He spoke only to confirm his name and address during the 15-minute hearing, during which he heard an outline of the prosecution case against him.
He was then led, head bowed, to a waiting prison van.
Defence solicitor Andy Smith made no application for bail and chairman of the bench, Keith Ford, remanded Obih in custody.
He was arrested on Monday morning following an incident outside Marks & Spencer in Luton town centre.
Mr Henry, who was wearing protective body armour, was seriously injured at the scene while answering the 999 call. He died from his wounds shortly afterwards.
