Elmo puppeteer Kevin Clash resigned from ‘‘Sesame Street’’ on Tuesday amid allegations he sexually abused underage boys, bringing an end to a 28-year career in which he turned the furry red monster into one of the most beloved — and lucrative — characters on TV and in toy stores.

‘‘Personal matters have diverted attention away from the important work ‘Sesame Street’ is doing and I cannot allow it to go on any longer,’’ the performer (inset) said in a statement. ‘‘I am deeply sorry to be leaving and am looking forward to resolving these personal matters privately.’’
