We continue to investigate two assaults in Bristol last night in which two men sustained serious injuries.
A man in his 20s was assaulted on Gill Avenue at around 6.50pm while a man in his 40s was attacked on Downend Road at around 8.30pm.
Both men are currently in a critical condition in hospital.
Road closures are in place around both locations to allow crime scene investigators to examine them.
Detective Inspector Mike Buck said: “I fully appreciate these two incidents are likely to cause concern among members of the public and I’d like to reassure them a thorough investigation is underway.
“While we are in the early stage of our inquiry we have reason to believe the two incidents are linked.
“There will continue to be a significant police presence in the area while officers carry out a detailed search of the scenes – something which they were unable to do during the hours of darkness.
“Anyone with any concerns about what happened is encouraged to speak to an officer at the scenes or contact their local neighbourhood team.”
DI Buck added: “I’d like to appeal for anyone who was in the areas of Gill Avenue and Downend Road last night who saw the incident, or anything else suspicious, to contact us.
“I’d also like to hear from anyone with footage of the incidents, such as that recorded on a dash-cam.
“I expect there could well be motorists who drove past the Premier Store on Downend Road who could have captured something important without realising and I’d ask people to review their footage and share what they have with us.
“Any information or footage you have, regardless of how insignificant you think it might be, could prove crucial to this investigation.”
