West Midlands Police have made a third arrest as part of their ongoing investigation into the disappearance of 34-year-old Reanne Coulson.

Reanne, who went missing last month, was last seen at approximately 9:46 p.m. in Coventry and is known to travel to Leamington.

In a development that signifies a new phase of the investigation, police have now arrested a third individual.

The 38-year-old was detained just before 4:00pm yesterday in the Coventry area on suspicion of perverting the course of justice.

Just as the suspect arrested on Tuesday (24 June), he remains in custody today.

Reanne's mother has today made an emotional plea, saying, "I just want my baby back."

Police have until late tomorrow to either release or charge the man who was arrested on Tuesday.

Detective Superintendent Jim Munro, from the Major Crime Unit, stated: "We are continuing to work relentlessly to find Reanne and obtain the answers that her family so desperately need.

"I know there are individuals in Coventry who possess information regarding her whereabouts.

"I urge them to come forward and speak with the police, or consider other channels such as Crimestoppers, where they can communicate completely anonymously.

"We are asking for any information that will help us locate Reanne, who we now sadly believe is deceased."
