Five men have been convicted of murdering a Polish father of three who died after being hit with a hammer and kicked in a Derby street.
Police said they still did not know why the men from Derby attacked Serioza Lawskoski, 29, in Normanton last April.
Imran Rashid, 29, of Madeley Street, Raja Jeelani, 26, of Depot Street, Robuel Islam, 25, of Loudon Street, and brothers Usman and Rizwan Ahmed, 19 and 23, were found guilty after a trial.
They will be sentenced on Wednesday.
The men were also found guilty of conspiring to cause grievous bodily harm against Mr Lawskoski, along with a sixth man, 21-year-old Kamran Ahmed, of Northumberland Street, Derby.
