CCTV captures gang of thieves in the act amid Grange Rd crime spree

CCTV footage has emerged showing a masked group smashing their way into businesses, as police arrest a 14-year-old and continue the search for other suspects.

Police are on the hunt for masked thieves after a spate of shop break-ins in the western suburbs.

Police were called to Grange Rd, Welland, about 12.10am on Sunday, following alarm activations at a group of shops.

Three businesses had been broken into and witnesses reported seeing three males running from the scene.

Police searched and arrested a 14-year-old boy nearby, however investigations are continuing into two outstanding suspects.

CCTV footage obtained by 7NEWS Adelaide shows a masked group smashing their way into a Grange Rd health studio at Allenby Gardens before targeting the skin care business next door.

The thieves smashed their way into the businesses, stealing money from cash registers and a mobile phone.

A nearby cafe was also targeted by the thieves on Sunday.

Awaken Health and Wellness Studio’s Samantha Goulter told 7NEWS the break-in was over in seconds.

“From the first one stepping foot in to the last one stepping out was 21 seconds, (they spent) more time breaking down the door,” he said.

A 14-year-old boy from Burton was arrested and charged with three counts of serious criminal trespass and three counts of theft.

He was refused police bail and appeared in the Adelaide Youth Court on Monday.

It comes after an Indian supermarket was also targeted on Grange Rd just last week while a cafe was also targeted in the same complex on Sunday night.
