Four people in the Philippines hacked into the accounts of AT&T business customers in the United States and diverted money to a group that financed terrorist attacks across Asia, according to police officials in the Philippines.

A statement from the Philippines Criminal Investigation and Detection Group, a law enforcement agency, said three men and one woman had been arrested in raids across the capital, Manila, last week.

According to the agency, the men were working with a group called Jemaah Islamiyah, a terrorist group linked to Al Qaeda and responsible for the 2002 bombings in Bali, which killed 202 people.

The group has been held responsible for several other terrorist attacks in Southeast Asia, mostly in Indonesia but including the Philippines.
