A robber who targeted a mum in her home was tackled and detained by her two sons who were sleeping upstairs.
The 58-year-old woman, who had been watching a film on TV, shouted for help when two masked men came into the house in Stretford.
The brothers, aged 28 and 32, came down the stairs and tackled one of the men while their mother, 58, called police.
The brothers continued to struggle with the intruder until officers arrived.
The struggle continued until he was arrested.
The second robber fled the scene.
Officers later found a loaded shotgun outside.
The two brothers were treated in hospital for minor injuries.
Today police were questioning the suspect, 27, who was being held on suspicion of aggravated burglary and possession of a firearm following the drama earlier today on Seymour Grove.
Detective Inspector Debbie Oakes said: "The occupants' extreme bravery coupled with our rapid response has led to the arrest of a suspect and I must commend the efforts of those involved, in particular the two brothers at the address.
"The fact we have recovered a loaded firearm demonstrates the offenders are serious criminals and I would urge anyone with information about those involved to contact us.
"It also means one less potentially fatal weapon is off the streets and out of the hands of criminals, which can only be a good thing for the people of Greater Manchester.
"We work hard to deter and investigate any incidents where innocent members of the public are threatened and attacked in their own homes and our latest crime figures reflect this, with domestic burglary and robbery offences both down by 14 per cent.
Anyone with information is asked to call Trafford CID on 0161 856 9168 or Crimestoppers, anonymously, on 0800 555 111.
