Police are investigating an incident in which a grenade was thrown at the home of a convicted drug dealer in Salford.
The grenade, which exploded at around 1am, caused damage to the front and windows of the home in Formby Street, Salford.
No one was injured during the incident, which police believe was a "targeted attack".
The address on the Duchy estate is home of Ryan Coward, who was sentenced to 32 months in jail after he was convicted of being concerned in the supply of cannabis. Coward lived at the house with his parents and brother, reported the Manchester Evening News.
Residents on the estate told of how they thought a "bomb had gone off" after hearing the explosion.
Detective chief inspector Clare Devlin from GMP's Salford division, said: "While we are only in the early stages of our investigation, we believe this was a targeted attack and can confirm that a hand grenade was used.
"Clearly this is something we are taking extremely seriously and I am sure people in the area will be hugely shocked by this news.
"There are a large number of officers dedicated to investigating exactly what has taken place here and they will also be speaking to residents in the local area today and over the coming days.
"Thankfully no one was injured during this attack, although the occupants of the address are understandably extremely distressed.
"Make no mistake that we are going to find out exactly what has gone on here and why, and catch those responsible.
"This kind of violent behaviour on the streets of Salford will simply not be tolerated."
