CCTV footage released by police shows the shocking moment an elderly man was kicked and tripped to the floor while he was doing his shopping in Morrisons.
A man - wearing a grey hoodie, black tracksuit bottoms and a black mask - can be seen walking into Morrisons in Eastwood.
As he headed over to the entrance, he approached an elderly man collecting a basket and kicked him in the legs.
The victim was knocked off his feet and fell heavily to the ground.
A number of staff members and shoppers saw the incident and checked to see if the man was OK.
The man in the grey hoodie walked out of the entrance and into the main part of the shop.
The incident happened at 2.40pm on Monday, March 29.
Less than a minute later, the man in the hoodie was seen leaving the supermarket.
PCSO Peter Keeley said: "We received a report that a man had been kicked and knocked to the floor, and, upon visiting the supermarket, we were able to review this quite shocking CCTV footage.
"The elderly man was simply going about his food shop and to have this happen to him is absolutely unacceptable.
"As part of the neighbourhood policing team, we're dedicated to listening to our communities, responding to reports and concerns and acting upon information we receive.
"And we would reassure people that officers will investigate wherever such a report is made and our enquiries into this incident are ongoing.
"We're keen to identify the man in grey and would urge anyone who recognises him or anyone who saw the incident to get in touch.”
Anyone with information is asked to call the force on 101, quoting incident 483 of April 1.
