The Secret Service and Metropolitan Police Department are investigating a suspicious package by 17th Street and New York Avenue, a MPD spokesman said Tuesday.

The MPD spokesman said the Secret Service called MPD for assistance in the investigation around 4:45 p.m. Tuesday.

Pedestrian and vehicular traffic was initially shut down near the Corcoran Gallery of Art on 17th Street but has since reopened, according to a GW email alert sent at 6:40 p.m.

An event at the Corcoran for Tuesday night was cancelled due to the police activity, according to the school’s Twitter account.

We're sorry to cancel tonight's event with Ahmed Mater due to police activity outside the Corcoran.
