A Christchurch photographer required stitches in his head and was left with a bruised cheekbone after he was assaulted by a man with a T-shirt concealing his face.
Photographer Don Scott from The Press was punched twice in the face and hit over the head with his camera during the assault.
He said he was "pretty shaken up" by the attack about 5pm on Tuesday.
Scott was waiting in a work car while his colleague conducted an interview at a Cass St property in Sydenham.
Earlier that day Scott had photographed a man who worked at the property.
While he waited, Scott saw a man wearing a fluorescent vest and a cowboy hat drive a vehicle from the property after picking up a passenger. The vehicle was a blue, four-door, four-wheel-drive Toyota with a well-deck and a fibreglass canopy on the back.
Less than two minutes later, the back door of Scott's car opened and a man punched him twice in the face and grabbed his camera. The man then hit Scott in the head with the camera and made off with it.
Scott described the attacker as a "heavily built" European man with a dark-blue T-shirt wrapped around his face and head.
Scott got out of the car and ran after the man. When he got to the corner of Durham and Sandyford streets, he saw the blue Toyota drive south along Durham St.
The camera that was taken was a black Canon 1D MkIV with a white Canon 100 to 400mm lens attached. The memory card in the camera is orange and has built-in wi-fi.
Scott was then taken to Christchurch Hospital, where he required stitches for a cut artery in his head.
"I was pretty shaken up," he said.
"I am very lucky. It could have been a lot worse than it was."
Detective Sergeant Ross Tarawhiti said police were still making inquiries.
They had spoken to a potential witness and intended to interview local businesses today.
"We are asking anyone that may have seen the assault to contact us.
"The man would have been quite distinctive with a blue T-shirt round his head," he said.
"We haven't got any strong lines of inquiry at this stage, but it is early days."
Tarawhiti asked anyone with information about the assault to contact him on 3637400, extension 37577.
