Spanish police announced the recovery of three of five stolen paintings by Francis Bacon on Thursday.

Five Bacon paintings valued at more than 25 million euros ($29 million) along with a safe with jewels and coins were taken from a Madrid residence in July 2015.

The works were stolen from a friend of Bacon while he was away in London.

Ten people have been arrested in the case so far. The theft began to unravel after a Barcelona resident contacted a British firm that specializes in stolen art with photos of the missing Bacons.
