Police in Birmingham are still appealing for information over the death of a man who was shot in the head on his doorstep last week.
They are still carrying out forensic tests and house to house enquiries into the death of 50-year-old unemployed Muhammed Yasin, who lived on his own in Whitehall Lane, Bordesley Green but have still to find a motive for the shooting on Wednesday, September 28, at 7.50pm.
Detective Inspector Tony Fitzpatrick who has been leading the investigation said: "There are over 50 police staff committed to tracking down the person or persons responsible for this clinical, calculated murder.
"It seems the intention of the attacker or attackers was to execute Mr Yasin and there is no information at this stage to suggest he was a victim of a robbery or a burglary. We are still examining exactly what took place."
"The family and the local community are fully supporting the police investigation.
"Shootings of this type are very rare but with the continued support of the community, the investigators will make every effort to bring the offender or offenders to justice.
"Anyone with any information or anyone who was in the Whitehall area of Bordesley Green at around 7.50pm last Wednesday, or anyone with information to assist the investigation as to the lifestyle of Mr Yasin should call 0845 113 5000."
