The light-heavyweight's emphatic win maintained his unbeaten professional record with a first-round knockout win, following a previous second-round stoppage of Liam Cameron.
Upon returning home from the fight, Whittaker claimed he had been burgled.
Whittaker stated that thieves stole several items, including his IBF belt, as he shared the negative news on Instagram.
Whittaker offered a "big reward" for information leading to the identification of the culprits.
