The Metro Transit Police Department has increased its patrols, K9 sweeps, and random explosives screening in the wake of the attacks in Paris and threats against D.C. allegedly made by the Islamic State.

The MTPD said in an email that it “continues to coordinate with its federal law-enforcement partners and monitor information regarding the tragic events in Paris.”

Riders will be able to observe an increase in police in the Metro system, which began on Friday evening and “will continue for an unspecified period of time.” More than 20 K9 teams are conducting sweeps and station entrances now feature random explosives screening. Officers can screen any bag or package brought into the Metro.

While the MTPD security inspection program has been in place since December 2010, it kicks into gear “when circumstances warrant heightened vigilance, such as an elevated security threat.”

MTPD said it has also implemented “other countermeasures that are not visible to the traveling public.”

The FBI Washington Field Office said in a statement that, “At this time, there is no specific or credible threat to the United States. We will not hesitate to adjust our security posture, as appropriate, to protect the American people.”

Metro Transit Police Chief Ronald Pavlik will speak at 3:30 p.m. at Gallery Place about WMATA’s “current security posture.”
