Police in London have released a man who was detained on Saturday after a car plowed through a group of pedestrians near the Natural History Museum, in what officials believe was a traffic accident and not a terror attack. Several people were injured, and the accident initially triggered a massive police response due to the similarity of the incident to terror-related incidents in the United Kingdom and throughout Europe whereby terrorists seek to mow down pedestrians at popular tourist spots. The U.K. has been on high alert for more terror attacks.
