Brisbane office stationery thief sought

Video has been released of a man with a distinctive moustache, who police believe is to blame for a spate of office robberies in Brisbane.

Police allege the man stole laptops, cash and other office equipment from about 20 offices in the CBD over the past 15 months, including several on Adelaide and Queen streets last weekend.

CCTV footage has been released of a man police want to speak to in connection to the alleged thefts.

He is described as Caucasian with a large build, a shaved head and a distinctive moustache.
