Pittsburgh police say 14 people from Greenpeace were arrested Wednesday on two of the city's bridges.
The environmental group unfurled a banner below the West End Bridge.
The banner warned of the danger to the planet's climate from carbon dioxide emissions. It was unfurled Wednesday morning and remained visible for a couple hours. Nine people were arrested there.
Police spokeswoman Diane Richard says five people wearing harnesses and preparing to rappel off another span, the Fort Pitt Bridge, also were arrested.
The 14 suspects faced various charges, including possession of an instrument of a crime, disorderly conduct, conspiracy and obstruction.
