A knife-wielding man has been arrested after running amok at an Asda supermarket.
Shortly after midday today, police were called to the store at Market Square, Ellesmere Port, following reports of a man causing disturbance.
The store was evacuated as he threw bottles and brandished a knife, which one eye-witness said appeared to be a machete.
He was aggressive and threatening towards officers, who then used an "incapacitant spray" before arresting him.
A police spokesman said: “During the course of the arrest a police officer received a laceration to his hand believed to have been caused by the knife.
“The officer has been taken to hospital by ambulance where the injury is being assessed.”
The arrested man is aged 59 and local.
He has been held on suspicion of affray and assault and taken to the custody suite for interview.
The Asda store is closed following the incident while officers carry out inquiries, and to allow the spray to disperse.
There are no reports of any members of the public being injured.
A male member of Asda staff received what is believed to be glass in the eye and has also been taken to hospital to be assessed.
Anyone who may have witnessed the disturbance should contact Ellesmere Port police on the non-emergency number 101, quoting incident 404 of 07/03/2014.
