Newport murder: Victim is Polish visitor Jerzy Dubiniec
Gwent Police investigating the murder of a 60-year-old man in Newport have named him as a Jerzy Dubiniec, a Polish man visiting the UK.
Ten people have been arrested so far after Mr Dubiniec was found on Broad Street, Pill, on Saturday.

Four people - two men, aged 22 and 44, and two women aged 18 and 46 - were also arrested on suspicion of causing death by careless and inconsiderate driving and failure to report a road traffic collision and released on police bail pending further inquiries.
