The door was blown off the phone box

The device was thrown at the call box near the junction of Daleswood Avenue and Broadway at 0050 BST on Saturday.

People living nearby were awoken by a loud explosion and saw two youngsters running away from the area.

Councillor Sandra Birkinshaw, from the South West ward, told BBC Radio Sheffield it resembled the scene of a grenade attack.

She said: "The roof of the telephone box has been blown off, with glass sprayed nearly up to the Broadway traffic lights.

"The door has been blown to the other side of the road.

"Now that is not a normal firework that does that kind of damage."

Councillor Birkinshaw, who says she was burned by a firework as a child, will be raising the issue at the next council meeting.

South Yorkshire Police have also been informed about the incident.
