A 21-year-old Israeli Arab man has been arrested by police on the suspicion he imprisoned his 19-year-old brother for three weeks in a room at their family home because of the younger sibling’s desire to convert to Judaism and join the IDF, the Hebrew news site nrg reported on Sunday.

Police received a tip about the situation last week from a female resident of the central Israeli city of Tayibe and went to the home to free the younger brother.

The older brother was not home at the time, but was found and taken into custody later.

He was brought to court for a remand hearing on Sunday.
