"One Arrest" is the seventh episode of the first season of the HBO original series, The Wire (2002-2008). The episode was written by Rafael Alvarez from a story by David Simon & Ed Burns and was directed by Joe Chappelle. It originally aired on July 14, 2002.

The Barksdale detail discuss the information they have garnered from their surveillance, with Prez showing a surprising gift for decrypting messages. They have identified a resupply with a specific time. Herc, Carver, Sydnor and Greggs make a labored arrest of the package carrier, but let Stinkum get away so as to not compromise the wiretap. Stinkum pages Stringer from outside the towers and Sydnor rushes over to photograph him as the call is returned, so they can legally monitor the phone call. In interrogation, Prez recognizes the carrier as Kevin Johnston, the boy he blinded in one eye. Daniels appeals to Johnston to contact him if he ever wants to change his life; Johnston mocks his offer.

McNulty and Pearlman meet with Phelan, who agrees to back the detectives. Phelan is surprised that Daniels stood up for the wiretaps, and worries that McNulty no longer trusts him since the Gant murder hit the newspapers. McNulty feels that he cannot trust anyone at the moment. Daniels attends a fundraiser with his wife, Marla. Also in attendance are Burrell and State Senator Clay Davis. Daniels finds himself in the kitchen with Davis’ driver, Damien "Day-Day" Price, who is viewing the house's valuables. He speculates about the profit that could be made until Daniels reveals that he is a police officer.
