If you found out someone you loved was doing drugs -- and you knew you could stop it -- would you grab a hammer and try to rescue that person???
That's the story behind the arrest of Tim Donaghy -- the ex-NBA ref who went to prison for fixing games.
Donaghy was arrested in Florida on Tuesday for allegedly threatening a man with a hammer ... but he told police the only reason he was even in that situation was to save his daughter.
According to the police report, Tim believed his daughter was doing drugs with a friend at a nearby home -- so he grabbed a hammer and went to get her.
