A factory worker who stabbed his estranged wife's lover to death in a frenzied attack in a Birmingham street in front of horrified shoppers has been jailed for life.

Saghir Ahmed carried out the "brutal" killing on the same day his wife was due to move in with father-of-six Amjad Khan.

Ahmed (29), of Ralph Road, Alum Rock, had previously admitted murdering 34-year-old Mr Khan.

David Crigman, QC, prosecuting, said Tanzeela Zulquarnain had had a relationship with Mr Khan before her arranged marriage with Ahmed which took place in Pakistan in 1999.

When she came back to England the secret affair continued until Ahmed became aware of what was going on after catching his wife speaking to Khan on the phone on a number of occasions.

He said on the afternoon of August 20 last year, Ahmed approached Mr Khan from behind as he was standing outside his video shop in Alum Rock Road.

A witness saw Ahmed strike out at him with a kitchen knife and then grab him so he could not escape.

Mr Crigman said Ahmed stabbed the victim eight times carrying on the attack as Mr Khan, who received a fatal heart wound, lay "totally helpless" on the pavement. Mr Crigman said the defendant drove away from the scene and that his burned out car was later found in Nechells.

Balbir Singh, defending, said there had been earlier provocation when his wife told him he was not the father of their five-year-old child.
