Yes, as Tonywiltshire has said there are Police station duty solicitors they are free if you are on a low income. Insist on the duty solicitor being present before you say anything . Phone the police now and and tell them you require the duty solicitor to be present so they can arrange it.
The duty solicitors are not connected with the police they are there to put your side , you will need to see the solicitor before talking to the police , this is normally done by the solicitor talking to you at the police station before the police have their say, the solicitor will stay with you for the interview.
