Between Wednesday, May 5 and Wednesday, May 12, there were two shootings on Manor Lane, Manor and one on Woodthorpe Crescent, Woodthorpe.
Detectives believed the incidents were ‘targeted’ attacks involving people with links to organised crime.
In the first on Wednesday, May 5, shots were fired between the occupants of two vehicles on Manor Lane.
The following day, police raided a house in the street as part of the investigation into the gun attack.
In the early hours of Tuesday, May 11, shots were fired towards the same house, causing damage to windows.
Just before 10.30pm on Wednesday, May 12 shots were heard in Woodthorpe and a search led to the recovery of shell casings and the discovery of minor damage to a house on Woodthorpe Crescent.
A 17-year-old boy was arrested on suspicion of two counts of attempted murder and firearms offences in relation to the incidents on Manor Lane. He has since been bailed while enquiries continue.
Detective Chief Inspector Paul Murphy said: “We know lots of people living in this area are concerned about the frequency of these events, and the subsequent increased presence of armed police.
“I would like to reassure you that we are treating these attacks as targeted, involving people who we believe have links to organised crime.
“We are now working tirelessly to detain those involved, but I cannot stress enough how much the support of our communities can help us progress our inquiry.”
