Two hammer-wielding robbers were confronted by a one-legged grandad in a mobility scooter after raiding a post office.
David Clough said he blocked the paths of two masked and armed men as they attempted to rob the Brown Avenue Post Office in Mansfield Woodhouse at around 11.30am today, Monday.
The 62-year-old said he intervened because the staff there are "really nice people".
"I was sitting outside the post office on my mobility scooter when this black Peugeot car came speeding around the corner and stopped outside," he told the Chad.
"One man got out of the car wearing a black balaclava and holding a hammer. He went inside and I heard shouting and screaming.
"I knelt on my mobility scooter so I could grab the guy who was about to come out.

"But then the driver came out and threatened me with a hammer. He said if I didn't get out of the way, there was going to be trouble, but I didn't move.
"I think after hearing the commotion the robber came out of the post office, and the two men fled with nothing."
On why he decided to intervene, Mr Clough said: "I really like them in the post office, they're really nice people. There was no way the robbers were going to get away with it."
Daughter Debbie said: "He is a hero – but I could have smacked him for getting involved."
A spokesman for Nottinghamshire Police confirmed that Brown Avenue Post Office was targeted by two masked robbers around 11.30am.
But detectives have said it is too early to say if the incident is linked to the robbery at another post office in Mansfield Woodhouse, in Station Street, on Saturday.
A spokesman for Nottinghamshire Police said: "Officers are currently investigating a reported attempted robbery at a post office in Mansfield Woodhouse.
"It was reported that two males wearing masks entered the property in Brown Avenue just after 11.30am today. It is believed that weapons were used but they fled empty handed and no-one was injured.
"They reportedly fled the scene in a dark-coloured vehicle. A burnt-out vehicle was recovered close to the scene. Inquiries are ongoing to ascertain if it is linked to the incident."
Anyone with information is asked to call police on 101, quoting crime reference 259 of April 24.

Anyone with information on this one is asked to call police 101, quoting incident number 306 of April 22.
