'Reprehensible': Man found in cupboard after allegedly speeding at 203km/h

A man allegedly detected driving at "extreme speeds" on an Adelaide road has been arrested after being found inside a cupboard.

The 21-year-old was reportedly driving on a suspended license and was recorded speeding at 203 km/h and 196 km/h in 80 km/h zones on Main North Road in Elizabeth Downs on August 10 and 13.

Traffic officers, assisted by a police dog, visited his address about 8.30pm yesterday and discovered him inside a cupboard before making the arrest.

SA Police Inspector Mark Atkinson said the alleged driving was "reprehensible".

"Speeding is a leading cause of fatal and serious injury crashes, and this driver has placed other road users at significant risk," he said.

The 21-year-old Elizabeth Downs man was charged with two counts of extreme speed and two counts of driving while suspended.

He was bailed to appear in the Elizabeth Magistrates Court on September 30.

Police are yet to find the Holden Commodore sedan.
