Police have arrested a man over a "random" morning shooting that left a woman in hospital.
A territory-wide search for the man using "full resources" led to the arrest in Weston Creek about 11am.
The shooting happened in Dominion Circuit, Forrest about 8.10am.
"A man got out of a car with a firearm and shot at the woman's vehicle," police said in a statement.
It appears two shots were fired at head-height, directly into the driver's side window. Police said she was "very lucky" to survive the attack.
Officer in Charge of Woden Police Station, Detective Acting Station Sergeant Simon Coady would not provide an age of the man or say where he lived, but did say he was known to police.
He also could not say what the man's motive was, but said drugs might have been a factor.
Police also found the car and weapon used in the incident in Weston Creek.
The man is expected to be charged with assault, robbery and firearm-related offences. He is being held in the City Watch house and is not expected to face court until Wednesday morning.
Earlier, the officer in charge of the scene at Manuka Oval, Superintendent Stephen Turnbull, described the incident as a "very random act".
"This type of thing doesn't happen in Canberra. This is very out of the ordinary," he said.
After the incident, the injured woman drove her white HSV Grange sedan to Manuka Oval, where preparations are underway for the international T20 cricket match between Pakistan and Australia, which starts about 7pm.
The woman, who had sustained gunshot and shrapnel wounds, flagged down security guards, who gave first aid. She was taken to Canberra hospital by ambulance with non life-threatening injuries.
Forensic crime scene investigators assessed the separate scenes at Forrest and at Manuka Oval for several hours. The woman's car was initially left at Manuka Oval with the glass of the driver's side window blown out. it was taken away by a tow truck after 11am.
The car park area off Dominion Circuit has been sealed off as a crime scene and officers are not permitting anyone to enter until further notice.
The shooting incident occurred about 150 metres from Telopea Park School, which went into lockdown.
"Our school acted quickly and appropriately to ensure the safety of our students and teachers," the school said in a letter emailed to parents.
Police officers were seen going into the school shortly after the shooting took place.
A NSW police spokeswoman said Queanbeyan officers were working with their ACT counterparts to establish whether there were any potential links between Tuesday's shooting and an incident that happened on Saturday morning in Queanbeyan, where a man was shot in apparent road rage incident on Molonglo Street.
In that case, Queanbeyan police said they were searching for a Caucasian man in his 30s who was driving a silver sedan at the time of the incident.
An ACT government spokeswoman said Tuesday's cricket match at Manuka Oval would not be impacted.
Superintendent Turnbull said the cricket match should be treated as normal by fans.
"We're treating [the incident] extremely seriously. We want to make sure that Canberra is a safe place," he said.
"We're doing everything we can and we're putting as much resources as we can to investigate the matter."
