Paul Morson murder inquiry: Four men arrested
Four Merseyside men have been arrested as part of an investigation into the disappearance of a St Helens man.
Paul John Morson was last seen in June 2011 in Huyton and was reported missing by his family shortly after.
Two men, aged 59 and 23, from Whiston and a 33-year-old from Huyton have been arrested on suspicion of murder and being concerned in the supply of controlled substances.
A 33-year-old from Anfield has also been arrested on suspicion of murder.
The arrests were part of a pre-planned operation by Merseyside Police.
In October, three men arrested on suspicion of the kidnap and murder of Mr Morson were released on bail.
