Multiple Annapolis neighborhoods were raided by a swarm of law enforcement agencies Wednesday following a “lengthy investigation” related to “drugs and gun trafficking” across the Maryland capital, according to an email shared with The Capital Gazette.

The early morning operation was part of a larger police action across the state and included parts of Anne Arundel County and Baltimore City, according to the FBI Baltimore Field Office.

The raid, as described by city law enforcement, was loud and expansive.

In a message sent to city council members, Annapolis Police wrote that starting around 6 a.m., constituents may see “huge convoys of about 20 SWAT teams” from multiple federal agencies.

They said approximately 20 search and seizure warrants and 16 arrest warrants would be served and warned residents they “will be hearing numerous flash bangs,” telling city officials to expect an increase in 911 calls.

In a statement, a spokesperson for the FBI Baltimore Field Office said 18 “court-authorized searches” were made in the three areas and that 14 unidentified suspects had been arrested.

It was not immediately clear which neighborhoods in Annapolis, Anne Arundel and Baltimore were affected by the raid. How many people were arrested in each area was also unclear.

Addressing city officials, Annapolis Police limited the subject of the investigation to “drugs and gun trafficking in the city of Annapolis,” but did not state whether a specific organization or gang was being targeted.

According to the email, an Annapolis Police task force “concluded” the local investigation, though officers from the FBI, Maryland State Police and other federal agencies provided support Wednesday.

A spokesperson for the FBI Baltimore Field Office did not provide further details on the ongoing investigation. Angelina Thompson, a spokesperson with the Maryland U.S. Attorney’s Office, said she could not confirm or deny the existence of any investigation.

Annapolis Police Chief Ed Jackson declined to comment Wednesday afternoon. A representative for the Anne Arundel County Police Department did not immediately respond to a request for comment, while the Baltimore Police Department deferred comment to the FBI.
