D.C. police have arrested the man whose abandoned gun discharged while Investigator Wayne David was trying to retrieve the weapon from a sewer, killing the officer.

Metropolitan Police told WTOP News that officers took Tyrell Lamonte Bailey into custody on illegal gun charges following his arrest around 10:30 p.m. Wednesday.

Mr. Bailey, 27, is accused of tossing his gun down a highway storm drain on Aug. 28 after he ran from authorities on the 4500 block of Quarles Street Northeast.

The gun went off as Investigator David was trying to fish it out of the drain. The veteran officer died in a hospital later that night.

Police said Mr. Bailey made good on his escape last week by hopping on the back of a passing motorcycle. Authorities said there was “no indication” the suspect and the biker knew each other.

MPD and federal agencies partnered to offer a $60,000 award for information leading to Mr. Bailey’s arrest.

Investigator David, 51, has been the focus of various memorials and tributes since his unexpected death.

His funeral is scheduled for Sept. 12 at Ebenezer AME Church in Fort Washington, Maryland.
