POLICE are warning Crosland Moor youngsters to be on their guard after a series of robberies involving a man with yellow teeth.
A man confronted two boys, one 15 and one 14, at a bus stop in Blackmoorfoot Road at 6.10pm on Tuesday.
He threatened to stab them and demanded money.
The man then went through the boys' pockets, stealing cash and a mobile phone from the 14-year-old and a watch from the other boy.
In another incident, a 16-year-old was robbed at 5.45pm the same evening in nearby Tom Lane.
The teenager was walking along the road when three young men approached him and demanded cash.
The victim was ordered to sit on a wall while the thieves rifled his pockets and took a mobile phone.
A scuffle broke out, the teenager snatched his phone back and the gang fled.
One of the attackers had a spotty face, yellow teeth and had black stubble around his mouth and chin.
At 7.30pm on Sunday two men stole an 11-year-old boy's rucksack, containing a camcorder, in Dryclough Road, Crosland Moor.
