A woman has been arrested on suspicion of grievous bodily harm and possession of a firearm after a police officer was shot with a sawn-off shotgun in Nottingham.
The 27-year-old was arrested alongside another woman and two men who fled after shooting the officer's foot in the early hours of Sunday.
The victim had approached two of the alleged assailants at a bus stop in the Radford area of the city centre, Nottinghamshire Police revealed today. He is currently in a stable condition after being treated in hospital.
Meanwhile, a cordon put in place around Angel Row - where the shooting took place - has now been lifted, though officers remain at the scene.
A sawn-off shotgun was found on the street, which is one of Nottingham's busiest and near the city's council building.
Assistant Chief Constable Claire Rukas, of Nottinghamshire Police, said: 'A team of experienced detectives continues to work tirelessly to establish exactly what happened before, during and after this appalling incident.
'I am pleased that four arrests have now been made and hope this provides some reassurance to the public as those detained are questioned in connection with the discharge of the firearm.

'The police cordon in Angel Row has now been lifted, and I would like to thank local businesses, residents and members of the public for their patience, support and understanding while officers carried out vital enquiries and recovered evidence from the scene.
'The injured officer continues to recover in hospital and is receiving support from colleagues and loved ones. We ask that his privacy is respected at this time.
'Our thoughts remain with him, and with his family, friends and colleagues, who have all been affected by this deeply shocking incident.'
The woman, 27, was arrested on suspicion of causing grievous bodily harm with intent and possession of a firearm with intent to endanger life.
A man, 24, and a woman, 25, were also arrested on suspicion of assisting an offender.
And, early this morning, officers detained a man aged 30 in Bedfordshire on the same grounds.
Nottingham East Labour MP Nadia Whittome wrote on X: 'My thoughts are with the injured police officer and his family following this truly shocking incident. We all wish him a full and speedy recovery.'
The Police Federation of England and Wales also sent its best wishes to the officer.
It said in a social media post: 'This is a stark reminder of the dangers police officers face every day while protecting the public.
'Their courage and commitment must never be taken for granted.'

The victim was being treated by another policeman outside a Taco Bell restaurant, with bouncers standing by him and a member of the public holding his foot as the reinforcements quickly arrived.
Crowds of bystanders then started gathering as traffic came to a standstill. Shouts and car horns were also heard amid the early morning chaos.
Nottingham was a gun-crime hotspot during the early 2000s and the city council even appointed a 'reputation manager' to remove the perception of it as an area blighted by gun-toting criminal gangs.
The crime rate in Nottingham as of this month is 1.4 per 1,000 people – or 143 per cent of the national crime rate.
