Police are warning revellers in Manchester not to take green ecstasy pills known as "green Rolex pills" after two people fell ill after taking the pills at the city's gay pride festival.
The partygoers took the tablets in the early hours of Sunday morning, police have said and they are understood to have suffered adverse side-effects. Their exact condition is not known.
The Manchester Evening news reported on the pair taking the drugs – which are florescent green and shaped like the luxury Rolex watch – and falling ill.
