Three people were admitted to hospital after taking an unknown red pill during a night out.

Police have issued a warning after the three suffered a severe reaction in Maidstone on Saturday night.

The trio all attended the town’s Urban Blue Bus and had symptoms including significant breathing problems, vomiting, a racing pulse and a high temperature.

All three required hospital treatment, and admitted to experimenting with a red, circular or star shaped pill that they had bought for the first time.

It is is believed to be known as ‘rockstar’.

A fourth person is reported to have taken the pill in Medway on the same night.

Chief Inspector Jon Bumpus, Maidstone District Commander said: ‘Taking any drug is dangerous and presents health risks, but these pills in particular appear to be unpredictable and could potentially have very serious consequences.

"We are carrying out a number of enquiries to glean more information."

The three have all now been released from hospital.
