State police say 13 protesters were arrested inside the Massachusetts State House for refusing to leave the building.

A department spokesman says troopers responded to the House Speaker's office after the building closed at 6 p.m. Thursday, where about 25 people had gathered in the reception area and were sitting in doorways and blocking paths.

Although some voluntarily moved, state police say some "had indicated beforehand their preference to be arrested."

Nine women and four men were arrested on trespassing charges. State police say they are expected to be released on personal recognizance.

The protesters were from a group called Movimiento Cosecha, which advocates for driver's licenses for all immigrants, where they are in the U.S. legally or not.
