A knifeman who stabbed a man twice in the chest is believed to have been involved in seven separate attacks in Birmingham.

All of the attacks have been in the Lozells area, and the description of the offender is similar in each case.

In the most recent, on Wednesday, a 40-year-old man was approached as he walked along Leonard Road at 7.15pm and was stabbed twice. He was not seriously injured.

All of the offences have been against lone adult men, aged 19 to 56. No motive has been determined but all of the incidents have happened very near to one another in Lozells since June.

None of the victims has been seriously injured. On each occasion, a knife has been used, or seen by the victim. Police patrols have now been stepped up.

The offender is described as black, between 18 and 30, slim and 5ft 8in to 6ft. The man has had his face covered for each assault.

Anyone with information should contact CID at Thornhill Road police station on 0845 113 5000.
