Police are linking two street robberies in Chorlton.
At around midnight on Sunday 15 April 2012, a 27-year-old woman was approached from behind on Hartington Road and was confronted by a man.
He demanded she hand over her handbag and threatened her, claiming he had a knife.
The man took her bag and walked off towards Corkland Road.
The second happened at around 1.15am as a 33-year-old woman walked along Corkland Road.
She was asked whether she had the time and when she replied no, the offender grabbed the victims handbag, causing her to fall to the floor, before he walked off.
The victim suffered minor grazes to her elbow.
The man is described as being white, in his late teens/early 20s and 5ft 6ins tall. He wore a black hooded top with a motif across the front and black trousers.
Detective Constable Pam Collins from South Manchester CID said: "This man has threatened and intimidated his victim's causing both to fear for their safety.
"Although no knife was seen, he did threaten the 27-year-old woman and said he would stab her if she did not give him what she wanted.
"If you were walking or driving in the Corkland Road or Hartington Road area at the time of both robberies and may have seen a man fitting this description, please get in touch."
