Police are investigating a break-in at the Forum Centre in Dundee.
The ‘Essentials’ store unit was broken into at around 8.35am on Monday 13 January.
The thief made off with £600 worth of ‘legal highs’ along with a two-figure sum of cash.
Officers are keen to speak with a 6 ft man in a yellow jacket who was last seen running out of the Commercial Street exit to the shopping centre.
Police Scotland Tayside Division are reminding people of the risks associated with taking ‘legal highs’.
A Spokeswoman said, “The dangers of these so-called ‘legal highs’ are unknown and mixing them with another drug, or alcohol, can result in even more severe consequences.
“These substances can be professionally packaged and branded, but this doesn’t remove the substantial risk to health.
“We would strongly advise anyone against consuming any psychoactive substances and would urge anyone suffering from adverse effects to seek immediate medical attention. Although the substances are marketed as “legal highs” they still carry warnings which state they are not for human consumption.”
Anyone who witnessed the incident is being urged to contact Police Scotland Tayside Division on 101 or speak to any police officer.
Information can also be passed on anonymously to Crimestoppers on 0800 555 111.
