The police did not identify the suspect but said he is an Arab expatriate in his 30s.

Officers acted on a tip-off about his suspicious activities and were able to catch him red-handed.

The police said the suspect was ambushed after a number of customers were monitored entering and leaving his place. They added an undercover police officer offered to buy $80,000 for SR150,000 from him.

“While showing the fake customer a counterfeited $100 bill, the forger was caught,” a police spokesman said, adding that materials for black magic were also found in his place.
