Today's traffic restrictions and planned roadworks in Ipswich

Why it matters: The investigation into the death of 63-year-old William "Billy" McNicholl, who was found dead in a Hawthorn Drive property on 1 January, continues as police seek justice for the victim and his friends and family.

A Home Office post-mortem indicated McNicholl died from head injuries and a single stab wound.

The details: Three people were arrested on Tuesday 1 April – a 17-year-old boy, an 18-year-old man and a 41-year-old man – on suspicion of assisting an offender and being concerned in the supply of Class A and B drugs.

All three have been questioned at Martlesham Police Investigation Centre and subsequently bailed to return to police on 1 July.

What they're saying: Detective Inspector Mark Hughes said: "A large number of officers have been involved in the investigation and many people, including residents in the Hawthorn Drive area and surrounding streets, have either contacted us or have been spoken to by our officers. However, if anyone has any information that they are yet to share with police, I would ask them to do so, to help us find out what happened to Billy."

He added: "Our enquiry into his death and the work to bring those responsible to justice continues."

The bigger picture: On 22 January, a 17-year-old boy was arrested on suspicion of murder. He has been bailed with conditions and is due to return to police on Tuesday, 22 April.

A woman in her 50s, previously arrested on suspicion of murder, has been told she will face no further action.

What's next: Crimestoppers is offering a reward of up to £20,000 for information given anonymously that leads to the arrest and conviction of those responsible.

Phil Breckon, Regional Manager at Crimestoppers, said: "Our charity is offering a reward of up to £20,000 for information given exclusively to us that leads to the arrest, charge and conviction of anybody responsible for Billy's murder."

He added: "If you have information, however small, please speak up and tell Crimestoppers 100% anonymously. If you prefer not to talk to the police, you can tell us what you know, and we'll pass it on for you."

The reward will expire on 30 April 2025.

The bottom line: Police continue to appeal for anyone with information to contact them quoting reference 37/162/25, either via the Major Incident Public Reporting Portal, by calling 101, or by contacting Crimestoppers anonymously on 0800 555 111.
