Control room staff, response officers and a member of the public joined forces to detain three suspects after an elderly man was robbed.
After spotting the incident in Bracebridge Drive, Bilborough, the member of the public immediately phoned 999 just before 10.30am on Tuesday (31 May).
She was then able to give key details that allowed police to track and locate a vehicle wanted in connection with the incident only 16 minutes later.
Two men aged 37 and 40, were arrested on suspicion of robbery and possession of class A drugs.
They remain in custody as enquiries continue.
A 33-year-old woman was also arrested on suspicion of robbery and possession of class A drugs. She has since been bailed with conditions.
The 78-year-old victim received minor injuries and is being looked after by his family.
Superintendent Sukesh Verma, of Nottinghamshire Police, said: “This must have been an incredibly scary ordeal for the victim who was simply going about his day.
“Thanks to the quick and clear thinking of a member of the public our 999 our call handler was able to quickly get vital information which proved key in finding and arresting the three suspects.
“Our call handlers play such an important part in what we do. Not only do they help our staff, but they are also that beacon of help and reassurance to the members of the public and victims in their time of need.
“This was really great work by everyone involved and I’m thankful the victim was not seriously injured.”
