PASADENA >> Authorities closed the Lake station of the Metro Gold Line and both sides of the 210 Freeway at Lake Avenue Wednesday after a man drew suspicion for getting on and off trains then threw what looked like a jacket on the carpool lane.

Deputies tracked the man to another Gold Line station in Pasadena. He fought with deputies and was arrested, according to Ramon Montenegro, spokesman for the Sheriff’s Transit Policing Division.

The Los Angeles County Sheriff’s bomb squad used a robot to pick up the jacket which ended up on the carpool lane of the eastbound 210. There was nothing found on the jacket, according to Deputy Ryan Rouzan.

All freeway lanes reopened at 10:43 a.m. The Gold Line Lake station reopened a minute after.

“The trains are back to normal schedule,” Metro spokesman Rick Jager said.

The incident started shortly before 9 a.m. at the station located at 340 N. Lake Ave. Montenegro said a man who was at the station acted suspicious.

“He was boarding trains and getting out of trains,” Montenegro said. “We sent deputies to the Lake station. When they got there, he had already left.”

Montenegro said before the man left, he threw an item from the station platform onto the 210 freeway.

Closed circuit television showed the man getting on a train bound for the Memorial Park station at 125 E. Holly St. Deputies found him there. Montenegro said the man, whose name has not been released, was arrested on suspicion of fighting with deputies.

A sergeant with a bomb-sniffing dog went out to check the clothing on the freeway. Montenegro said the sergeant notified the sheriff’s Arson/Explosive Detail.

The California Highway Patrol shut down the eastbound and westbound lanes at Lake Avenue. Metro closed the Lake station.

Jager said Metro turned back trains at the Allen and Memorial stations. He said they used six buses to shuttle riders between the stations.

A 25-year-old man who only gave the name “Alexander” said he was on the Gold Line train traveling from Azusa around 8 a.m. when the conductor told passengers “we have complications at Lake Station” and everyone would have to exit.

As he exited the train, he said he saw a black duffel bag on the shoulder of the 210 Freeway’s eastbound lanes.

The Pasadena Police Department closed off Lake Avenue from Corson to Walnut Street by 10:30 a.m.

The Gold Line trains were not running.

“Now I’m just sitting here, waiting for the trains to open up,” Alexander said as he sat on the curb near the Gateway Plaza office building, smoking a cigarette.

An unsubstantiated bomb threat led to enhanced security on Metro’s Red Line on Monday and Tuesday. The FBI said late Tuesday that investigators found no evidence to verify that a bomb threat to L.A.’s subway system was credible.

“Based on significant similarities, law enforcement partners also believe the anonymous caller may have, on a previous occasion, reported threats that did not materialize. The Joint Terrorism Task Force will continue to investigate to determine the identity of the caller and will continue to evaluate information developed from investigative efforts,” FBI spokeswoman Laura Eimiller said in a statement.

The task force announced Monday night a specific and imminent but uncorroborated threat in which an anonymous male in a foreign country called a public safety hotline and said that an “attacker would detonate something” at the Metro’s Red Line Universal City Station Tuesday, Eimiller said.
