A Washington state physical education teacher has resigned following allegations that he texted teenage students nude photos of himself.

The Yakima Herald-Republic reports that Zachary Joseph Sybouts faces two charges of communicating with a minor for immoral purposes.

The Grandview High School teacher has been on paid leave since April, when police began their investigation. Grandview Superintendent Kevin Chase says Sybouts will be paid until his contract is up at the end of the school year.

Investigators say a 16-year-old student reported Sybouts said he wanted to kiss her and sent her sexually explicit photos. Two other students, ages 16 and 17, reported similar allegations, with one saying Sybouts kissed her on campus.
