A man has been arrested on suspicion of several offences in the car park of a drop-in clinic and community centre.
The disturbance took place at the St George's Centre in Middleton at around 10am this morning.
A 24-year-old man was arrested in relation to an earlier domestic assault, possession of drugs and driving a vehicle while unfit. He is currently in custody.
