BATH, Maine (AP) Police say the number of protesters arrested outside Bath Iron Works during a weekend ship christening was the largest in many years.

The Bath Police Department arrested 25 people on Saturday, accused of blocking a road. Chief Mike Field said everyone was cooperative, and no one was hurt. He said the number of arrests was the largest since at least the early 1990s.

The activists were calling on the federal government to spend money to fight climate change instead of building warships. They demonstrated as the daughters of Lyndon B. Johnson were christening a warship that bears the late president’s name.

All 25 were charged with obstructing a public way, a misdemeanor. They’re due to appear in District Court in West Bath on June 18.
