New plea over Shumin Hussain's 2003 St Albans flat plunge
The family of a man whose death sparked a murder inquiry 10 years ago have re-appealed for information in the hope of getting "justice and closure".
Shumin Hussain died after falling from a window at a block of flats he was visiting in St Albans, Hertfordshire, on 7 September 2003.
At the time a number of arrests were made, but no-one was ever charged.
Hertfordshire Police said there were no new lines of inquiry but the force would "never" close the case.
Mr Hussain, of Doggetts Way in St Albans, died from multiple injuries after the ninth floor plunge at Telford Court.
Detectives believe the key to the 29-year-old's death lies with a number of people who were involved in a disturbance at the flat shortly before he fell, just after 22:00 BST.
Forensic teams had scaled the outside of the tower block in an attempt to gain evidence as part of the original inquiry.
Mr Hussain's family said: "We miss him ever so much and know that someone must be able to help us.
"It has now been 10 years since he died and we are keen to get justice and closure.
"We as a family plead to you to come forward and help if you have any information at all."
Mick Flavin, from the police force's cold case team, said: "The case will never be closed and we remain in contact with Shumin's family as, understandably, they are keen to find out the full circumstances surrounding his death.
"I would encourage anyone who knows anything which would assist with our inquiries to contact us".
