An Edmonton teacher is facing two additional charges of sexual assault that are alleged to have occurred at pools. 

Christopher Herodek, 48,  was charged earlier this month with inappropriately touching girls in the pool at the Terwillegar Recreation Centre over the Christmas holidays.

On Thursday, police announced new charges in similar incidents involving two pre-teen girls at pools in north and west Edmonton in 2009.

Edmonton Public Schools confirmed that Herodek taught with the district.

He was suspended when the first set of charges were announced on Jan. 10.
