Parents have been warned over cannabis infused gummy bears "which look like normal sweets" after pupils were rushed to hospital.

Metropolitan Police issued a warning to schools in Sutton after a number of pupils were made "very ill" after buying them.

It is believed that the first few incidents took place on March 12 and the sweets have continued to be sold throughout last week.

Greenshaw High School shared a letter online after they received a safeguarding message from Met Police.

It said: "There has been an increase in young people buying what at first appear to be regular jelly sweets, gummy bears or similar sweets.

"These sweets are not what they appear to be. They are in fact mixed with cannabis and have a detrimental effect on those eating them.

"Sadly, a number of school pupils in Sutton have been either made very ill or hospitalised as a result of eating them."

Students found in the possession of the sweets will be directed to the police.

Parents and pupils who come across the sweets are being urged to contact authorities on 101 or 999.
