Brazilian President Jair Bolsonaro was hospitalized Monday evening after a fall in the presidential residence, his office said.

Bolsonaro was taken to the armed forces’ hospital in the capital of Brasilia and underwent examinations of his skull that showed no problems, said a statement from the presidency’s communications office.

The president would remain under observation for six to 12 hours, it said.

The statement gave no other details on the incident, but Brazilian media reported that Bolsonaro slipped  in the bathroom and banged his head.

Earlier this month, Bolsonaro reportedly  told advisers that he felt extreme tiredness and asked for his agenda to be reduced through the end of the year.
