Detectives are appealing for witnesses to come forward following a robbery in Runcorn.
At around 10.45am on Thursday 13 June a 21-year-old man from the town was walking a dog in Bog Wood at the bottom of Walsingham Drive in Sandymoor when he was assaulted from behind.
The victim lost consciousness and did not see who attacked him.
He woke up to discover that he had sustained a head injury and his mobile phone had been stolen.
The victim was taken to hospital via an ambulance and has since been discharged.
Enquiries in relation to the incident are ongoing and detectives are urging anyone who was in the area and witnessed the robbery, or saw anything suspicious, to get in touch.
They also want to speak to anyone who believes they may know who committed the robbery.
Detective Constable Nathaniel Walkowiak, of Runcorn Local Policing Unit, said: “This was a frightening incident that has understandably left the victim extremely shaken up.
“The head injury he sustained as a result of the incident could have been much worse and I would like to reassure residents that we are doing all we can to catch whoever assaulted the victim and took his phone and bring them to justice.
“Enquiries are ongoing and as part of our investigation we are appealing for anyone who was in the area and witnessed anything that may be relevant to contact the team here at Runcorn Police Station.
“We particularly want to speak to two males estimated to be aged between 18 and 20 who were seen in the area around the time that the incident occurred.
“We also want to hear from anyone who believes they may know who was responsible for the robbery.”
