Los Angeles, March 17 (IANS) Singer-actor Frank Sinatra Jr has died following a heart attack. He was 72.
The singer died on Wednesday afternoon, reports tmz.com.
The son of the legendary singer Frank Sinatra was due to perform a concert of his father's songs at the Peabody Auditorium in Daytona Beach, Florida on Wednesday night, but the event was cancelled after he fell ill.
He had cancelled his show after complaining of feeling light-headed and was later admitted to hospital where he suffered a cardiac arrest.
His sister Nancy shared the news of his death, and posted on Facebook: "The Sinatra family mourn the untimely passing of their son, brother, father, uncle, Frank Sinatra Jr., of cardiac arrest while on tour in Daytona, Florida. Sleep warm, Frankie."
Sinatra Jr was famously kidnapped in Lake Tahoe in 1963, when he was 19 years old for a ransom of $240,000.
He was released two days later after his father paid the amount demanded by the kidnappers, who had also demanded all communication take place via untraceable payphones.
He is survived by son Michael Sinatra and sisters Nancy and Tina Sinatra.
Singer Tony Bennett led the tributes, tweeting: "I am deeply saddened to hear of the passing of Frank Sinatra Jr and send my sympathy to Tina and Nancy and the Sinatra family."
