Police have released the image of a man they wish to speak to in relation to two recent armed robberies on the Sunshine Coast.

Around 6.30pm on September 22, the man entered a Ninderry Road, Yandina restaurant and threatened staff with a firearm. He fled the scene with a sum of cash.

He was wearing a high visibility yellow and a blue short-sleeved collared shirt, baggy dark green or brown shorts and a red bandana across his face.

Just before 8.30pm on the same evening, the same man then attended a takeaway store on Steve Irwin Way at Glasshouse Mountains.

He threatened staff with a gun, but this time left empty-handed.

He fled the scene in a white single cab four wheel drive tray back utility.

During this incident, he was wearing blue t-shirt with a white motif on the front, dark blue work trousers, tan work boots, a red bandana across his face and a blue one across his head.

He is described as being Caucasian in appearance, approximately 182cm tall, of a slim build with brown hair and blue eyes.
