A reward of £10,000 is being offered by Crimestoppers for information on the murder of Molesey mother Robyn Mercer.

Ms Mercer, 50, a mother-of two and an antiques dealer, was found bludgeoned to death in her front garden in Abbey Walk, Walton Road on Monday, March 14.

A post mortem examination found she had died from multiple blows to the head.

The Crimestoppers charity is now offering the reward for information leading to the arrest and conviction of those responsible.

Julia Hughes, regional manager of Crimestoppers in Surrey, said: “No one will ever know you contacted us.

“Please do the right thing and help get justice for Robyn and her devastated family.”

Surrey Police said on Thursday that two of the men previously arrested on suspicion of murder, had been rearrested on suspicion of conspiracy to burgle and commit murder.

One of the men has been bailed until June 28 while the other remains in police custody.

A 44-year-old woman and 20-year-old woman from Oxshott, were also arrested on Thursday morning on suspicion of conspiracy to pervert the course of justice.

Both have been bailed until June 28.

A 52-year-old man, arrested on suspicion of murder the day Ms Mercer’s body was found remains on bail until May 19.
