In the wake of today’s explosions at the finish line of the Boston Marathon, Metro security is on a heightened state of alert while normal Metro bus and rail service continues.

Metro passengers are likely to see or encounter extra patrols by the Los Angeles Sheriff’s Department, which provides security for the Metro system. This may include bomb sniffing dogs at Los Angeles Union Station and other Metro facilities.

Metro reminds the public: “See Something, Say Something” to report any suspicious activity or unattended packages. In order to contact the Sheriff’s Department, call 323-563-5000 or press the intercom in rail stations to speak to law enforcement. Passengers can also seek Metro personnel who are present on many rail platforms.
