Suffolk Police will be working with pubs and clubs this weekend to highlight the dangers associated with a drug that has been linked to two deaths.

A red triangle shaped pill with a Superman logo has been found to contain the dangerous ingredient PMMA and officers will be engaging with communities and the night-time economy across the weekend to raise awareness of the drug.

Superintendent Louisa Pepper said: 'Our number one priority is to prevent other people suffering the tragic consequences of this dangerous drug. Over the weekend we will be talking to people who are in the bars and clubs in Ipswich to advise them of the danger. We'll also be out and about in the local communities, handing out leaflets and making sure that as many people as possible know not to take these pills.

'We successfully seized a large quantity of drugs but there may still be some out there so if you do come across them please don't take them, and if possible hand them over to us.'

More than 400 red triangle shaped pills with a Superman logo were found in a public place near the Norwich Road, Ipswich on Sunday. It is believed that this type of drug could be linked to the deaths of two young men in Ipswich. The death of a third man, In Rendlesham, is being investigated.

Testing on the drugs has revealed that they contain PMMA, a stronger and more dangerous active ingredient than those usually found in ecstasy.

Councillor Alan Murray, Suffolk County Council's cabinet member for health and adult care, said: 'Following a death in Norfolk recently, we are especially concerned that people will think any pills that don't match the description of the red Superman pills are somehow safe. That would be wrong. There are other designs of pills in the illegal market that could be just as lethal.

'If you have taken illegal drugs, or if you know someone who has become unwell after taking illegal drugs and needs urgent medical care, call 999 immediately and ask for the ambulance service.'

Anyone in possession of the drug is asked to surrender it to police, in person or by calling 101, or at the following local agencies in Ipswich: CRI, St Matthews Street, MVA Team, 70 - 74 St Helens Street and the Fire Service, Princes Street.

If you have information about the supply of this or other illegal drugs call Suffolk Police on 101 or pass information anonymously via the Crimestoppers charity on 0800 555 111.
