(Normandy, France) -- A two-thousand-year-old relic said to contain the blood of Jesus Christ has been returned by thieves who stole it. The "Precious Blood of Christ" golden shrine was taken from a church in Normandy, France on June 2nd. Police believe the thieves stole the relic after locking themselves in the church overnight. A Dutch detective known for recovering stolen art said he was contacted by the thieves anonymously three weeks ago. They left the relic on his doorstep, and he planned to hand it over to Dutch police this week.
