British po­lice were hold­ing a 53-year-old man on Tues­day over a col­li­sion that turned a joy­ous soc­cer cel­e­bra­tion in Liv­er­pool in­to tragedy and sent more than two dozen peo­ple to hos­pi­tals, four of them in very se­ri­ous con­di­tion.

Mersey­side Po­lice said they are not treat­ing the in­ci­dent as ter­ror­ism and are not look­ing for oth­er sus­pects. The force has not iden­ti­fied the ar­rest­ed dri­ver. Po­lice in Britain usu­al­ly do not name sus­pects un­til they are charged.

De­tec­tives were work­ing to piece to­geth­er how a mini­van ploughed in­to crowds pack­ing a nar­row street, just af­ter the play­ers of Liv­er­pool Foot­ball Club had cel­e­brat­ed the Pre­mier League cham­pi­onship with an open-topped bus pa­rade.
