Cheshire Constabulary is appealing for information from the public following an incident in Warrington.
At around 4.40pm on Thursday 11 April police were called to reports of a small firearm being seen and discharged near The Greenwood pub in Greenwood Crescent.
The man with the firearm was witnessed being chased by two other males riding bicycles.
As a precaution, armed officers attended the scene. They made a thorough search of the area and carried out house-to-house enquiries but there was no trace of anyone.
There have been no reports of any injuries that could be linked to this incident and officers are trying to establish if the firearm was a genuine weapon or not.
Enquiries in relation to the incident are ongoing and officers are urging anyone who was in the area and witnessed anything that may help with the investigation to get in touch.
They also want to speak to anyone who believes they may have CCTV or dashcam footage of any of the males, or information regarding their identities.
Chief Inspector Simon Meegan, of Warrington Local Policing Unit, said: “We have launched an investigation following reports of a small firearm having been discharged in a public place during daylight hours.
“This has understandably caused concern in the local area and I want to reassure Warrington residents that we are taking this extremely seriously. We are doing everything we can to establish exactly what has taken place.
“At the current time this appears to be an isolated incident.
“There have been no reports of any injuries in relation to the incident and enquiries are ongoing to establish whether it was a genuine firearm or not.
“We have stepped up patrols in the area to provide reassurance and as part of our enquiries we are keen to speak to anyone who was in the area and witnessed anything that may be relevant to the investigation.
“We also want to hear from anyone who believes they may know who any of the males involved in the incident are or have CCTV or dashcam footage of them.”
The man who was being chased was white and is estimated to be in his late 30s. His hair is described as long, brown and scruffy and he was wearing high-visibility orange trousers and a grey T-shirt.
The two males on bikes were also white. One had a stocky build, a bald head and was wearing a blue coloured Puffa-style jacket and the other had short dark hair.
Anyone who believes they may know the identities of any of the males, or have any other information or CCTV footage that may aid the investigation, should call Cheshire Constabulary on 101, quoting IML 371477, give the details via https://cheshire.police.uk/contact/general-enquiries or contact Crimestoppers anonymously on 0800 555 111.
