A man with a knife robbed two teenagers in two separate incidents, 10 minutes apart, in Parklands, on Monday afternoon this week.
In the first incident, a man, described as bald, dark of complexion and wearing jeans, approached a teenager walking home from school and asked him for the time.
Police spokeswoman Captain Adriana Chandler said that when the boy took his phone out of his pocket to check, the man threatened him with a knife, grabbed his phone and ran off.
A man fitting the same description did the same thing to another teenager a few minutes later in Wood Drive.
Anyone with information is asked to contact Table View Police Station on 021 521 3300 or Crime Stop 08600 10111.
