Harvey Weinstein was back in the hospital before the end of the first day of his 23-year sentence for sex crimes. The 67-year-old, who was sentenced in New York Wednesday, was transferred from the Rikers Island jail complex to Bellevue Hospital hours later after experiencing chest pains, a rep tells Page Six. Juda Engelmayer says Weinstein will probably be kept in the hospital overnight for treatment for "ongoing heart problems" and "a complication related to his back surgery." After he was found guilty of rape and sexual assault last month, Weinstein was taken directly to the hospital, where doctors inserted a stent, CNN reports. He was later transferred to the Rikers infirmary unit. (More Harvey Weinstein stories.)
