A journalist and activist from Preston Hollow was convicted of causing “alarm and distress” last week after holding a banner reading “kill cops” at a protest in London earlier this year.

Barrett Brown wrote on Twitter that he received a fine of 1,200 British pounds.

Law enforcement in the United Kingdom began investigating Brown after he was photographed holding the banner at the April 3 protest.

Brown was arrested and charged with public disorder and incitement charges in May, the weekly newspaper reports. He made bail but was arrested by immigration authorities for allegedly overstaying his visa.

He was convicted of the lesser charge Friday and posted a 33-minute reaction video on Twitter on Tuesday. He said in the video that he was held for two days without a phone call after his arrest and that he wasn’t deported because he asked for asylum from the United States.

He also points out that the person who originally published the photo on Twitter was not charged with any crime, and Brown says he didn’t know what the banner said. It originally said “cops kill” but was rearranged.

Brown won (and then burned) the National Magazine Award in 2016 for a series of columns written for The Intercept titled The Barrett Brown Reivew of Arts and Letters and Prison.

The 40-year-old attended Preston Hollow Elementary and the Episcopal School of Dallas.

In 2015, he was sentenced to five years and three months in federal prison for convictions of accessory after the fact, obstruction of justice, and threatening a federal officer related to the FBI’s investigation of the 2012 Stratfor email leak. He was released from prison in 2016.
