PORTLAND, Ore. -- A Corvaliis man has been accused of sexually abusing two juvenile girls at his Tigard business, which provides private religious instruction.

Muhammad L. Hasan, 50, was arrested at his home and jailed on seven counts of sex abuse, according to Tigard police.

The abuse reportedly began in 2016 when the girls were Hasan's customers at his business, AICQ (American Islamic Center for the Holy Quran), which provided private instruction on the Quran, police said Thursday.

Hasan ran the business out of a storefront at 11505 SW Pacific Highway in Tigard.

Investigators think there may be additional victims. Anyone with information about possible abuse is asked to call 503-718-COPS (2677) or send an email to tips@tigard-or.gov.
