Lam was accused of pressuring a man, identified in court as X, to delete images from his phone. Protesters had suspected X of taking close-up photos of demonstrators during a protest outside the police headquarters in Wan Chai.

In January 2023, a District Court judge had acquitted the defendants of most charges, stating Lam was acting as a peacemaker to de-escalate a tense situation. The judges on Friday agreed, noting that while deleting pictures could obstruct investigations, there was no confirmation the pictures actually existed.

Lam, a former member of the now-defunct Democratic Party, is currently serving a prison sentence after being convicted in the Hong Kong 47 national security case in May 2024.
