Following Tuesday's subway shooting in Brooklyn, N.Y., in which a gunman deployed a smoke bomb, then shot at least 10 people on a busy train car, multiple major U.S. cities with public transit were beefing up security and monitoring for any signs of similar violence.
In the Brooklyn shooting, 16 injuries have been reported in total, including the 10 riders who were shot, some of whom were in critical condition.
As descriptions and photos hit the web and the airwaves, the Washington Area Transit Authority (WMATA) tweeted out its full support of New York City and its people:
"We're horrified by this morning's event @NYCTSubway & continue to monitor security of our system w/heightened awareness; there are currently no known credible threats. Be vigilant & report any suspicious behavior immediately to MTPD at 202-962-2121 or text MYMTPD (696873) #wmata."
A WMATA spokesperson also informed WTTG-TV of an extra safety measure it would be taking: "Additional K-9 sweeps and patrols are being implemented in the system as a precaution."
In southern California, the Los Angeles Police Department has increased its "high-visibility" patrols throughout the city, particularly at its many bus and rail stations.
The LAPD tweet said the agency "is closely monitoring reports of a multiple victim shooting this morning at a subway train station in Brooklyn. We're in contact with our local, state & federal partners, and as always, providing high-visibility patrols throughout the city, including bus & rail stations."
In Illinois, the Chicago Transit Authority (CTA) has likewise taken steps to bolster monitoring of its own travel network.
Chicago was already looking at a particularly busy day aboard its transit system, with the the Chicago White Sox baseball club set for its home opener at Guaranteed Rate Field, located just south of downtown.
Chicago has also seen a spate of shootings and homicides in recent months, which has already had city officials on alert.
"While there is no actionable intelligence at this time, CPD will maintain the appropriate resources to ensure safety on the public transit system," a Chicago police spokesman said in a statement to WFLD-TV.
Meanwhile, New York police continued an intensive manhunt for the culprit in its subway shooting, seeking -- and by some local accounts, finding -- a U-Haul truck with Arizona plates said to be somehow connected to the mayhem.
The suspect remained at large as of the time of this publication.
