BANGKOK (AP) — Thai police were still searching for two out of four officers allegedly involved in trying to extort two Italian tourists by locking them up in a hotel room and demanding a 2 million baht ($62,600) ransom, authorities said Monday.

The four policemen and one Uzbek accused Danilo De Vito, 51, and 62-year-old Antonio Di Muro of using a fake card to withdraw cash at an ATM machine in Bangkok's tourist area of Nana and held them overnight at a hotel down the street last week, said Police Maj. Gen. Seubsak Phansura.

He said they robbed the two Italians of cash worth 1,500 euro ($2,000) but failed to get the ransom.

"The suspects wanted 2 million baht in exchange for them not to file the false charges against the Italians," Seubsak told The Associated Press. "They were locked up for 10 hours to wait until they could do financial transactions in the morning, but the Italians managed to call their relatives who then informed the police."

Two officers surrendered on Friday and their bail requests were rejected over the weekend. The Uzbek man, Muhiddin Sharipov, was also arrested on Friday.

The other two remained at large and police believed they had not fled the country, Seubsak said. He added all four officers were fired from the police force.

The five will face charges of armed robbery, armed kidnapping and armed extortion, which can carry the death penalty.
