A 75-year-old man stabbed to death yards from his home may have been targeted in a racially motivated attack, according to police.
Mohammed Saleem, who used a walking stick, was stabbed three times in the back as he returned home from prayers at his local mosque in Small Heath, Birmingham, on Monday night.
The blows were struck with such violence they penetrated to the front of his body.
The father of seven also had no defensive wounds in what has been described as a swift, vicious and cowardly attack by the man leading the murder investigation, Detective Superintendent Mark Payne of West Midlands police.
Officers want to trace a white man, aged 25-32, of medium height and build, spotted on CCTV footage running near the scene of the attack around the time it happened, just before 10.30pm.
