A weapon used to stab a man to death at a Bedford flat has still not been found.
Police have reissued their appeal to the public to check their gardens, wheelie bins and hedges for a knife or other sharp instrument.
It comes more than a week after John-Mark Duffy, 39, died in the back of an ambulance at Wordsworth Court in Byron Crescent, Bedford, after being stabbed in the chest.
A Beds Police spokesman said: “There has been no progress in locating the knife. We are interested in speaking to any residents who come across anything like that in their gardens, in their wheelie bins or in their hedges.
“We advise them not to touch it and to contact us immediately.”
Following the death Ian Brunner, 47, of Byron Crescent was charged with murder. He appeared at Luton Magistrates Court last Wednesday where he was remanded in custody. He is due to appear at Luton Crown Court on May 5, when he is expected to submit a plea.
