EAST NORWALK - Commuters were on edge today as trains were searched in two southwestern Connecticut communities as part of the search for the missing suspect in the Boston Marathon bombings.

Witnesses on the train that was stopped in East Norwalk say officers from several different local law enforcement agencies searched the train with their guns drawn.

News 12 Connecticut is told that Boston authorities asked them to perform the search after the suspect was allegedly spotted getting on an Amtrak Train in Boston around 5 a.m.

Later, someone reported seeing the suspect on a Metro-North train, which was stopped and searched in Darien.

Police say nothing suspicious was found on either train. However, they're urging residents to be vigilant and to report anything that seems out of the ordinary.

The suspect,  Dzhokhar Tsarnaev, has since been found and is in police custody.
