Three men have been arrested after a distraction grenade was thrown at a house before shots were fired elsewhere in two suspected targeted attacks in Salford.
Greater Manchester Police have stepped up patrols after the incidents in the early hours of Friday morning.
Bomb disposal officers had to carry out a controlled explosion on what they described as a distraction grenade which was thrown at a house in Beech Lawn Close.
Police said the offender fled towards Eccles Old Road after the incident shortly before 12.30am.
Around 50 minutes later police received a report of shots fired on Quayview in Salford Quays, and found evidence consistent with a firearm having been discharged.
Three men, aged 20, 22 and 26, have been arrested on suspicion of possessing a firearm with intent to endanger life and causing damage to property with intent to endanger life. The trio remain in custody.
Detective Chief Inspector Amanda Delamore said their investigation was still in the early stages.
She said: “We continue to believe that these were targeted attacks and extra patrols remain in place in the surrounding areas. Please do approach them with any questions or concerns you may have.”
She urged anyone with information to come forward.
