In wake of the tragic attacks that occurred in Boston, the Los Angeles County Metropolitan Transportation Authority (Metro) has intensified patrol on transit and stations and is urging all transit passengers to be aware of their surroundings.

The L.A. County Sheriff's department has launched a new web site, TransitWatchLA.org, to inform the travelling public about what to look out for and who to contact when they suspect or encounter terrorist activities. The web site emphasizes the importance of "See Something, Say Something". If riders see any unusual behavior, suspicious objects or an unattended package, it should be reported to local law enforcement officials immediately. The easiest way to contact the sheriff's department is to call 911 or (888) 950-SAFE (7233). Riders should be ready to provide detailed description of the unattended item or suspicious behavior, the exact location and transit information.

The LAPD will also enhance their security for the upcoming CicLAvia on Sunday. There will be extra patrols and undercover officers at the event. All participants should remain alert of their surroundings and report anything suspicious to the LAPD.
