A frame-grab from cctv of a man depositing the Otago Museum's dinosaur egg in the central Dunedin Police Station yesterday morning.
Security footage from Dunedin central police station, where the egg was returned at an unattended counter yesterday morning, and from the museum led police to believe it was an Invercargill man, Senior Sergeant Bruce Ross said.
• Stolen fossilised egg returned
Invercargill police had been informed, and would talk to the man.
Staff noticed the fossil missing from the Dunedin museum's ground-floor shop.
The hadrosaur egg was 145 million to 65 million years old and valued at $1700.
