TOMS RIVER - An Ocean County school teacher has admitted having a sexual relationship with a 15-year-old student.

Ocean County prosecutors say 32-year-old Erin Haskell, of Barnegat, pleaded guilty yesterday to sexual assault. She will have to register as a sex offender and faces up to 10 years in prison, but will remain free on $300,000 bail until she's sentenced.

Haskell was a Spanish teacher with the Toms River Regional School District. She worked at the Intermediate South School in Beachwood. Authorities have said the relationship took place last year, between June and September.
