An investigation has been launched after a man from Haywards Heath was arrested where he became unwell and later died in hospital.
Police attended an incident on Saturday 26th July and restrained a 32-year-old man leaving the area by putting him into a police van - where he became unwell.
He was removed from the van just after midnight on Sunday morning and CPR was performed.
He was subsequently transferred by ambulance to a nearby hospital where he died earlier today.
A post-mortem has yet to be conducted and HM Coroner has been notified.
Following this incident a 32 year old man tragically lost his life and my thoughts are with his family and friends at this time. The IPCC will carry out a robust and thorough investigation into the circumstances and nature of his contact with the police, the events leading up to his becoming unwell and his hospitalisation.
"I would urge anyone with any information about this incident or anyone who witnessed any part of the police contact with the man to come forward to the IPCC as soon as possible.”
