Police have issued a warning after thieves on mopeds committed a spate of robberies in and around the city centre.
The crime spree is identical to one in January this year when riders snatched mobile phones around Manchester city centre and Salford .
And last year commuters were targeted around Victoria Station, Manchester Arena, and the Green Quarter in another series of robberies.
This time the victims were in Ancoats and Cheetham Hill .
In each case yobs on a motorcycle or scooter have mounted the pavement to snatch mobile phones from unsuspecting victims.
In one case a 29-year-old woman was robbed on Jersey Street in Ancoats as she walked home on Thursday evening by two men.
The victim said: "It was 9.20pm and I was walking from Aldi back to my flat. I had a big bag of shopping and I went to put my headphones in my phone and I was putting music on.
"I was walking down Jersey Street and I saw a friend in front of me walking his dog. Then I heard beeping from behind and could see someone had come up onto the pavement.
"I turned round to see what was going on and was annoyed that they were on the pavement but they had the moped light on full beam and all I could see was a bright light.
"As they went passed they both had balaclavas on but one had a skull print on the balaclava - he grabbed the phone out of my hand. He was wearing gloves and was the pillion passenger.
"I think my friend's dog may have put them off as the one of the back of the moped shouted to the driver 'don't stop'.
The thieves escaped with an Apple iPhone worth £700.
"They went down Jersey Street towards Radium Street. I was a bit shook up."
Amazingly the victim saw the thieves again 24 hours later. "I saw them twice on the Friday evening go past the Pen and Pencil bar in the Northern Quarter like they were doing laps of the block.
"There were two bikes this time - with two people on each - and one was wearing the same skull print on the others were wearing balaclavas or hoods covering their face. That was between 6 and 7pm on Friday evening.
"The police told me that on the night I was robbed there had been a few incidents. I am not bothered about getting the phone back I just don't want it to happen to other people. The police said there were four or five incidents that night."
The thieves were also seen riding down Blossom Street on Thursday towards Cutting Room Square which is ringed by restaurants and bars.
In another incident a would-be thief on a motorbike attempted to steal a mobile phone from a woman, but crashed with a van when he rode away.
The motorbike rider mounted the pavement on Waterloo Road, in Cheetham Hill, and tried to snatch the phone.
But while trying to escape he collided with the van.
Emergency services were called to reports of the smash at 4.45pm on Thursday.
