The FBI has placed billboards on state highways to assist in the manhunt for the suspect in the Boston Marathon bombings.
Police in Massachusetts have found a 1995 gray Honda Odyssey that might be connected to a suspect in the Boston Marathon bombings, according to Connecticut State Police.
The car has Massachusetts license plate 93NN73.
Earlier, police have recalled a a "be on the lookout" alert for a 1999 green Honda Civic, with Massachusetts registration 116 GC7.
It turns out that car had been in the possession of Massachusetts authorities since Friday morning. Massachusetts state police quickly recalled the alert after realizing the car was not missing.
Gov. Dannel Malloy said, via Twitter, on Friday afternoon that emergency management officials in Connecticut are continuing coordinating efforts with Massachusetts and federal officials.
An accomplice or associate of the suspect was believed to have taken a train to Connecticut, which appeared to have been stopped and surrounded at East Norwalk, NBC News learned.
Connecticut state police said police stopped a train that was traveling from Boston to Stamford as a precaution, since it was coming from Boston and stopping so close to New York City.
Officials from the Metro-North Railroad Metropolitan Transportation Authority issued a statement saying Amtrak's Acela train #2151 was stopped at 8:22 a.m. in East Norwalk.
The Norwalk police SWAT team and MTA police, searching for a person of interest in the Boston situation, swept the train and the search turned up no results and the train was allowed to proceed at 9:16 a.m.
Metro-North's New Haven Line was suspended in both directions from 8:36 a.m. to 9:16 a.m., and trains are now running with residual delays.
MTA officials said they are increasing patrol coverage and bag inspections.
State police issued a news release this morning saying they received information from the Boston Investigation that a gray Honda CRV, with Massachusetts license plate 316 ES9 could be occupied by a wanted suspect and issued a bulletin at the request of Massachusetts authorities.
That car has been recovered in Boston, according to Connecticut state police.
Connecticut state troopers are posted strategically in the state and continue to communicate with Massachusetts authorities.
"We will offer our full support to our neighboring state and assist in any way we can," Malloy said via Twitter.
