Several children collapsed at a high school after eating cakes that had been laced with cannabis, according to reports.
Police quizzed a 16-year-old girl after her friends fell ill at Shirley High in Croydon, south London.
Staff called ambulances after they were told the teenagers had eaten super-strength skunk brownies, reports The Sun.
A source told the newspaper: “She baked the brownies at home with skunk weed and took them into school the next day and stashed them in her locker.
“The girl gave them out to friends at lunchtime and a short while later they began falling ill
The brownies were full of skunk grass and would have been the equivalent of smoking several really strong joints.”
A statement from the Metropolitan Police said: “Police were called at 2.56pm to a school in Shirley Church Road, Croydon, on Friday, 29 March, after a number of students reported feeling unwell.
Officers attended the school with LAS where six pupils had been taken ill.

The Sun reports that none of the children who ate the cakes suffered permanent damage.
