It comes as police have named 52-year-old Leszek Migdal, also known as Peter, who died outside Freemantle United Reformed Church this summer.

Police were called to Shirley Road shortly after midday on Saturday, August 19, by medics at South Central Ambulance Service due to concerns over his welfare.

He was sadly pronounced dead a short time later. His death was initially thought to be unexplained but not suspicious. 

But a month later detectives confirmed a 46-year-old man had been arrested on suspicion of murder with a major investigation underway. The man has been released on bail.

Today Leszek's sister has issued a heartfelt plea. In a statement issued via Hampshire police, she said: “In remembrance of my beloved brother Peter, whose death came as a painful mystery.

“We are reaching out to anyone who may have even the smallest piece of information related to his passing, as it would greatly help us to find solace in saying our final goodbyes.

“Even though the circumstances he found himself in were tough, we always wanted the best for him.

“Peter will be remembered as life continues for us, we love and will miss him a lot.”

In the aftermath of his death, police treated the matter as unexplained but not suspicious.

Following new information which came to the attention of officers in September, a murder investigation was launched and a 46-year-old man from Southampton was arrested on suspicion of murder in connection with Leszek’s death.
