"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 cloned pagers and wiretap, with Roland "Prez" Pryzbylewski showing a surprising gift for decrypting messages. They have identified a resupply with a specific time. Detectives Herc, Ellis Carver, Leander Sydnor and Kima Greggs make a labored arrest of the package carrier, but let Stinkum (the driver) get away so as to not compromise the wiretap. Stinkum pages Stringer Bell 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 in Episode 2. Lieutenant Daniels appeals to Johnston to contact him if he ever wants to change his life; Johnston mocks his offer.

Detective McNulty and ASA Rhonda Pearlman meet with Judge Phelan, who pulls McNulty up in his poor grammar, but nonetheless decisively agrees to back the detectives. He then flirts with Pearlman, but when she leaves he opens up to McNulty and asks him to respond. Phelan gives support to McNulty - phone calls at "50 cents a pop" no longer work.

Phelan is surprised that Daniels stood up for the wiretaps, and worries that McNulty no longer trusts him since the murdered witness story 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 Deputy Commissioner Ervin 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.
