A Spaniard is in police custody after the appearance of parts of the body of a Colombian friend of his with whom he was traveling in the landfill on the island of Koh Phangan, in Thailand.

Daniel Sancho Bronchalo, 29, was taken this Friday to the Koh Phangan police station for questioning about the disappearance of his friend and has denied any connection to the case, the Bangkok Post newspaper reported.

A day before, he had gone to the same police station to report the disappearance of his friend, at which time the garbage collectors had already found human remains, including a pelvis and cut-out intestines, inside a sack of fertilizer.

On Friday, they found more human remains in a black bag, this time along with a black T-shirt, a pair of shorts, and a pair of red underpants.

The police officers who went to the place together with the forensics suspected that the parts could belong to the Colombian man.

Investigating officers discovered that Sancho had purchased a knife, rubber gloves, a kitchen sponge, a cleaning pad and a bottle of detergent on Tuesday.

Upon checking their hotel room, they realized that the refrigerator, bathroom, and kitchen sink had been washed, but in the drains they found traces of blood, grease, and hair.
