Darien police arrested a half-naked man running through traffic on New Year's Eve and charged him with sexual assault.
Police said they got multiple calls about Adonnus Elliott, of Norwalk, walking on Noroton Avenue.
A victim told police she had been sexually assaulted by Elliot and kicked him out.
Elliott ran from officers and into traffic.
He was eventually caught and taken to a hospital to be evaluated.
Police say Elliot was staying with that victim at the time.
