The three boys are being held on suspicion of attempted murder.
Three teenage boys have been arrested on suspicion of attempted murder after a 12 year old was shot in Deighton on Tuesday.
A 17-year-old boy was arrested in Almondbury and a 16-year-old boy was arrested in Dalton overnight on suspicion of attempted murder.
A third boy, aged 16, was also arrested Thursday morning on suspicion of the same offence. All remain in custody today for questioning.
Officers were called to Northfield Hall at about 7.15pm on Tuesday evening following a report of an incident there.
A short time later a 12-year-old boy presented at hospital with injuries consistent with a firearms discharge.
He remains in hospital for non-life threatening but potentially life changing injuries.
He had walked outside the centre with friends when a male suspect, who had arrived outside the centre with another three males, discharged a firearm.
Immediately after the firearms discharge it is believed a second male, aged 13, was threatened by a man carrying a knife.
The victim, who was not attacked with the knife, fled and fell over, suffering a minor injury
All four suspects are believed to have fled the scene in a BMW. This was later found burnt out in the Edale Avenue area of Newsome in Huddersfield.
Detective Chief Inspector Vanessa Rolfe of the Homicide and Major Enquiry Team, said: “We are very much continuing to appeal for witnesses as our investigations continue into this very serious incident which we are treating as attempted murder.
“Three males have been arrested following enquiries and detectives and specialist police units are continuing to conduct operations across the Kirklees area today.
“I want to thank members of the public who have got in touch with us so far. I continue to ask anyone who can assist our enquiries in relation to the firearms discharge or the car being abandoned to come forwards.”
She added: “We are particularly keen to speak to a witness who we think was present in the Edale avenue area at the time the BMW was abandoned and was set on fire.
“He was wearing a high vis jacket and seen chatting to paramedics parked up in a nearby ambulance so may have witnessed the car being abandoned.”
