Police investigating the robbery of a Dunedin store say numerous pieces of wood with nails protruding from them found near the store seem related to the crime.
A man wielding a firearm robbed the Night' N Day store in suburban Mornington just before 8am yesterday.
A "significant quantity" of tobacco and cigarettes was taken, along with a small amount of cash.
"Police haven't ruled out that these items may have been brought to the scene and were of significance for the offender," Detective Sergeant Rob Hanna said. "When he was running away towards Macnee St and onto Henderson St after the robbery he was seen to throw a piece of wood with nails protruding from it, at a nearby vehicle with people in it.''
The offender was still on the loose today, and police said they had particular interest in his behaviour 90 minutes before the robbery.
"A man closely fitting his description was seen in a white sedan car (make and model unknown) between 6.30am and 6.45am in Henderson Street, which runs behind the dairy on the south side of Eglinton Road," Hanna said.
The alleged offender is male, and possibly in his twenties. He is believed to be Caucasian, 175-185cm in height, and of slim, athletic build.
He was wearing a distinctive multi-coloured hoodie with a white background and coloured design, and three-quarter trousers and boots. He was carrying a number of bags.
The offender's left arm appeared to have markings on it.
Police have spoken to several witnesses, but say they want to hear from anyone else who may have information about the robbery.
"This was a brazen act that occurred at a busy time of the day in a busy part of town when there were many people around. Someone who hasn't yet come forward may have seen something that will assist in solving this crime," Hanna said.
