A police spokesperson said: “Our investigation is ongoing to establish what happened. A 36 year-old man was treated for injuries to his arms and arrested at the scene. He received medical treatment at hospital over the weekend and has now entered custody where he is being questioned by detectives on suspicion of murder, coercive or controlling behaviour, and criminal damage. At a virtual hearing with Portsmouth Magistrates Court this afternoon (Wednesday 3 January) a warrant of further detention was granted to allow detectives further time to interview the man until Friday 5 January.
An IOPC spokesperson has confirmed it has received the referral. They said: “We have begun an independent investigation into contact that police officers had with Joanna Derkacz in December 2023 prior to her body being found on 28 December in Waterlooville, Hampshire. Our investigation began following a mandatory referral from Hampshire and Isle of Wight Constabulary and will look at the prior police contact, including the actions and decision making of the officers involved. Our investigation is in its very early stages and we will keep all parties updated as the investigation progresses. Our sympathies are with everyone affected.”
