Police have put reports of gunfire in Hethersett down to 'cluster fireworks'.
The National Police Air Service helicopter joined Norfolk Police in a search of open farmland behind the village at around 1am this morning, after residents claimed to have heard gunfire and screaming.
At around 2.20am the helicopter was stood down with no persons found and searches this morning, which included armed officers and the police helicopter, did not locate any items relating to firearms.
However, investigations revealed a bonfire and fireworks which are believed to make a similar sound.
Sgt Zoe Hardman, Diss Police Station, said: 'We are grateful for everyone who has contacted us so far regarding this incident and ask if they have any further information to call us directly.
'While it appears that on this particular occasion there may be an innocent explanation, it is not always the case and anything believed to involve firearms should always be reported to police.'
Those living in the village reported hearing a woman screaming and gunshots over a two-hour period - with one resident claiming to see a man chasing a woman around the field.
Anyone with information regarding the incident should contact Diss Police Station on 101.
