A 34-year-old man is in a serious condition in hospital after being shot by police in the south of Glasgow.
The shooting happened in the Mount Florida area
An armed response unit was sent to the Mount Florida area following reports that a man with a pistol had held up a nearby convenience store.
The shooting happened in Somerville Drive, close to Hampden Stadium, at about 2200 BST on Saturday.
An investigation by another police force has been launched to check if guidelines were followed correctly.
A report will then be sent to the procurator fiscal.
It is not known where on the body the man, who has not been named, was shot.
Nobody else was injured and the man was then taken for treatment to the Victoria Infirmary.
It is believed that the incident took place 30 minutes after police were called to a robbery at the Spar shop on Cathcart Road, about 50 yards from the western end of Somerville Drive.
Shop owner Tahir Hamid said that the man, who was known to the staff, had ordered a bottle of vodka and a packet of cigarettes before putting a gun to the chest of a member of staff.
Mr Hamid said: "The staff thought he was messing around. They said 'don't be stupid'.
"He just said 'give me the bag'. Then he walked out."
The shop owner said that the incident was "bizarre".
"It seemed like the guy was on some kind of war path. Something clicked. He didn't hide his face. He wasn't hiding anything," Mr Hamid said.
Staff called the police after the incident and they studied CCTV pictures.
Deputy chief constable Ricky Gray, of Strathclyde Police, said: "As a force we take the issue of deployment of armed officers very seriously and we are well aware of the potential consequences of dealing with incidents involving firearms.
"The rigorous training our officers receive aims to minimise any risk to life."
The appointment of a senior officer from an external force is normal procedure in such cases.
The review by the investigating officer will aim to determine if guidelines set down by the Association of Chief Police Officers were followed.
