At approximately 1900 local time (1800 UTC) 20 June 2020, a 25-year-old man armed with a knife stabbed a number of people in the Forbury Gardens public park in central Reading, located approximately 65 km (40 mi) west of downtown London. Eyewitness reports indicate that the assailant moved between groups of people at the park attempting to stab them. At least three people were killed, including a U.S. national, and three others suffered non-life-threatening wounds during the attack. Police officers arrested the assailant at the scene; the individual is reportedly of Libyan origin and has been known to authorities since at least 2019 for suspected aspirations of traveling abroad for terrorism purposes. Authorities believe that the perpetrator acted alone and are further investigating the terrorist attack.
