Police are appealing for information after a woman was sexually assaulted on a Jubilee line train, with officers seeking a man described as wearing a Super Bowl-branded baseball cap. The incident adds to ongoing concerns about passenger safety on the London Underground, where transport police regularly urge witnesses to such offences to come forward.

Specific details of the assault, including its date, time and the exact route or stations involved, were not included in the available report. Investigators are relying on the distinctive cap as a key identifying feature in their search for the suspect, and further details are expected to be released as the police investigation progresses.
