PITTSBURGH (AP).- Pittsburgh Public Schools officials are investigating an impromptu field trip of sorts that occurred when two 6-year-old students wandered away from their school and walked to the city's Children's Museum a few blocks away.

District spokeswoman Ebony Pugh says she can't specify what sort of discipline officials at Martin Luther King Elementary School will face for the incident Monday, because that's a personnel matter.

A museum spokesman tells WTAE-TV (http://bit.ly/KcnmKo ) that the students showed up at the museum about 2 p.m. Monday and asked if admission was free. When they were told no, the students ran into the museum until they were caught by security guards.

The school was locked down after a teacher noticed the students were missing.

Pugh says the school is developing a plan to prevent future incidents.
