MORRISTOWN - A former Morris County teacher accused of molesting several of his first-grade students has been indicted on numerous charges.

Jason Fennes faces three counts of aggravated sexual assault, eight counts of sexual assault and four counts of child endangerment in the indictment handed up yesterday by a Morris County grand jury.

Prosecutors say the incidents occurred between 2005 and 2008, while the 39-year-old Bloomfield resident taught at the William Mason Elementary School in the Montville Public School District. His alleged victims were four female pupils between the ages of six and seven.

Fennes was first arrested in March 2012.
