A man was robbed of his moped at knifepoint in Whitefield after he was parking it at an address on Elms Road on Saturday afternoon.
He was approached by three men with their faces covered.
One of them threatened the man with a knife and demanded he hand over his keys.
The man was able to run behind a locked gate at the property, whereafter the three offenders made off with the moped – pushing it away from the property.
The moped was found abandoned a few minutes later a short distance away on Devon Mews and returned to the owner.
The first offender is described as white, around 5ft 10ins tall, slim, aged between his mid-teens to early twenties and was wearing a blue hooded top with a grey face covering.
The second offender is described as around 5ft 10ins tall, slim and was wearing dark clothing with his face covered.
The third man was around 5ft 6ins tall and was wearing dark clothing.
No further descriptions of the men are available at this time.
Detective Constable John Dineen of GMP’s Bury District said: “Thankfully the man was able to escape uninjured after being confronted, and his bike was recovered a short time later.
“We are keen to speak to anyone who saw this incident take place, or who has any information that might assist our investigation.
“While we have limited descriptions of the offenders, this incident occurred during daylight in a built up residential area.
“The offenders would likely have been visible pushing the moped for a short period after the robbery, before abandoning it.
“Were you in the area at the time, or did you see something that appeared unusual? If so, please get in touch.”
