We are appealing for information following reports of three robberies in Farnborough in the early hours of Wednesday 29 August.
The incidents took place during a 30-minute period between midnight and 12.30am that day.
In the first incident, a 15-year-old boy was in the playpark in Totland Close when he was approached by a group of men.
They threatened him and he handed over an iPhone 6S. The boy was not injured during the robbery.
In the second incident, two men approached a car that was parked in the car park in Moor Road.
They demanded items from a 23-year-old man and a 23-year-old woman before dragging them out of the car.
The man was assaulted and sustained a chipped tooth. The offenders left with cash and a mobile phone.
In the third incident, a 38-year-old man was threatened and then assaulted by three men on a footpath between Wren Way and Moor Road.
They stole £15 cash, a phone, a set of keys and a moped that the victim had been pushing at the time.
The man sustained a small cut to his forehead in the incident.
