Police: Connecticut trains shut down Friday morning

New Haven Line train service was delayed for nearly an hour Friday morning, April 19, as police investigated a possible link to the suspects in the Boston Marathon bombings. But are running again, according to Metro-North Railroad.

A Metro-North train conductor alerted Darien Police to a suspicious person on the New Haven-bound train from the Noroton Heights Station on Friday morning, according to Darien Police Sgt. Jeremiah Marron.

All of Boston is shut down Friday morning as police search for a second suspect in the Monday Boston Marathon explosions that killed three people and injured 176.

Dzhokhar Tsarnaev escaped Thursday night, and the second suspect, Tamerlan Tsarnaev brother of the first, was killed in a shootout with police in Watertown, Mass., a Boston suburb, overnight.

Friday morning, State Police in Connecticut were also scanning highways for the gray Honda CRV the suspect is believed to be driving. It was later found in Boston.

Sgt. Marron told The Darien Times, a Hersam Acorn newspaper, the police department met the train with the suspect passenger at the Darien train station along with the MTA's emergency services and bomb sniffing dogs.

The police located the alleged suspicious person and the person "checked out," according to police. The train was swept by the dogs and the police and was released to continue by 10:30, Marron said.

There was additional police activity at the South Norwalk train station Friday morning but the two incidents were unrelated, according to police. Reports say police searching trains and highways is related to the manhunt for a suspect in the Boston Marathon bombings.
