A teacher in Northern California has been disciplined for making threatening and explicit remarks about students on her Twitter account.

The Newark Unified School District gave a written reprimand to Newark High School teacher Krista Hodges, who tweeted between April and June that she wanted to stab and pour coffee on some of her students, according to the Oakland Tribune (http://bit.ly/1Cb0beT ).

In one tweet she said some students "make my trigger finger itchy."

Interim Superintendent Tim Irwin says he consulted state education law, the Newark school board's policy and the teacher's union contract before disciplining Hodges.

Newark police are also investigating.

Hodges, who continues to teach at the school, says she deeply regrets sending the tweets and never expected anybody would take her seriously.

She has since deleted her account.
