Police arrested four people and seized an air rifle that was fired in the street.
The rifle was reportedly aimed at and shot towards some bushes in Hucknall Lane, Bulwell.
Multiple policing teams descended on the location when the call came in, around 5.50 pm on Wednesday (19 June).
Armed Policing and response officers attended on the ground, while the National Police Air Service (NPAS) supported from above.
Four suspects were quickly detained by police following the report, which resulted in no injuries.
An airsoft rifle matching the description of the firearm seen was then found in the boot of a nearby car and seized.
Three men, aged 28, 20 and 18, were all arrested on suspicion of discharging a firearm within 50 feet of a highway.
A fourth suspect, a 32-year-old man, was also arrested on suspicion of possessing a firearm without a certificate.
Detective Chief Inspector Claire Gould, of Nottinghamshire Police, said: “As the public should be able to expect, Nottinghamshire Police will always take immediate and robust action whenever we receive reports of a suspected firearm being seen.
“This incident should serve as a warning to any weapon carrier – and that includes anyone with an imitation firearm – that we will treat reports of this nature extremely seriously to help keep people safe.
“While the firearm involved in this incident proved to be an airsoft rifle, we hope the swift response of our policing teams to this sighting provides the public with some reassurance that we will take action.
“Four suspects have been arrested in connection with this offence, but our inquiries are still ongoing, so we’d ask anyone who saw what happened, or has any information to get in touch with the police.
“Information can be left by calling 101, quoting incident 602 of 19 June 2024, or can alternatively be left anonymously by calling Crimestoppers on 0800 555 111.”
