FORT LAUDERDALE, Fla. (AP) - A former Broward Sheriff's Office lieutenant has been sentenced to five years in federal prison after pleading guilty to conspiracy for his role in convicted Ponzi scheme operator Scott Rothstein's $1.2 billion fraud.
    
U.S. District Judge James Cohn imposed the sentence Monday on 48-year-old David Benjamin.
    
Court documents show Benjamin was paid about $185,000 for assisting Rothstein in several ways, including having another lawyer's ex-wife arrested falsely to gain advantage in a child custody fight. Former BSO detective Jeff Poole is being sentenced Thursday after pleaded guilty to civil rights conspiracy in that arrest.
    
Prosecutors say Benjamin also told other deputies to force a female escort to leave the state when her boyfriend threatened to expose her relationship with Rothstein partner Stuart Rosenfeldt.
    
Rothstein is serving 50 years in prison.
