IPCC investigation after woman dies in Brighton
Sussex Police is under investigation after a woman collapsed on a street in front of officers and died later in hospital.
The Independent Police Complaints Commission (IPCC) said it was investigating an incident in the Kemp Town area of Brighton on 17 February.
The IPCC said the 36-year-old woman collapsed in Lavender Street after "interacting with police" at 16:50 GMT.
The woman was taken to hospital but died three days later.
A post-mortem examination is due to be carried out.
It is understood that two plain-clothed PCSOs on foot and one police officer in a marked police vehicle were initially involved, and four further officers subsequently attended.
A 34-year-old man was arrested at the scene on suspicion of a drugs offence.
The IPCC has appealed for any witnesses to come forward.
