Police are appealing to the public for CCTV or dash cam footage as they investigate the death of a man found in a South Dunedin street.

A neighbour understands there was an "altercation" before he was found in Leckhampton Court, off South Rd, late on Wednesday night.

Cordons have been in place for most of Thursday as police examined the scene. 

Detective Senior Sergeant Hayden Smale said on Thursday night that this had been completed.

A section of Leckhampton Court between South Rd and St Helliers Court had reopened and all cordons removed. 

Inquiries were continuing and he appealed for any information.

"Investigators are particularly interested in hearing from anyone who observed anything unusual in the Leckhampton Court area between 8 and 11pm on Wednesday night.

"Anyone with CCTV or dashcam footage from the area during that timeframe is urged to contact police."

‘Altercation’ before man found dead

Earlier, a Leckhampton Court neighbour said police had spoken to him about whether he had seen anything between 10.30 and 11pm on Wednesday.

"They said there was an altercation on the street, and if we heard or saw anything, we have to tell them," he said.

"They want to know about that suspicious activity, if anyone saw it."

"[They said] they don't know who it was yet, and that it was suspicious."

Officers took CCTV footage from the resident's home.

The man said he heard sirens and when he looked outside he saw ambulance staff performing CPR on a man in the street.

"It was intense. It was scary for the person, you know, I wasn't thinking about myself."

The Otago Daily Times spoke to multiple other residents in the area, all of whom said they did not hear any sirens or police approach while they slept.

Another resident said she was quite concerned she would not be able to walk down the road, and instead would have to walk up a hill.

One man said there was a body in the middle of the road, and police were investigating.

In October 2016, a man was stabbed in the neck at a Leckhampton Court boarding house.

Anyone with relevant dashcam or CCTV footage was asked to contact police via 105, referencing file number 261001/3548. Information could also be provided anonymously through Crime Stoppers on 0800 555 111.
