A BOMB made of nails exploded after being thrown at a home on Friday night.
The explosive device was flung at a residence on Bloomfield Road area in east Belfast city.
Just before midnight, the bomb exploded upon impact on the house and scattered nails and shrapnel all over the front garden.
No one was injured in the attack on the house but one woman, who was inside, was left severely shaken by the ordeal.
Neighbours were asked by police to stay towards the back of their houses as Ammunition Technical Officers stabilised the device and secured the area.
PSNI officers investigating the incident said they were looking for two males who were seen riding mountain bikes in the area between 11pm and midnight.
Detective Sergeant Rory McPhillips of the PSNI appealed to anyone with information to get in touch. He said: "Anyone who witnessed any suspicious activity in the area around the time of the attack should contact detectives at Musgrave by calling the non-emergency number 101, quoting reference number 1633 of 18/5/18."
