Suspect accused of robbing three Dallas banks in FBI custody

A suspected serial bank robber is behind bars, accused of holding up at least three Dallas banks.

Investigators say in each case, he threatened employees with a kitchen knife. Two of the robberies happened in the same day.

Dallas police say the man seen on surveillance images inside the Capital One Bank branch in Old East Dallas demanded cash while he held the knife against an employee's back. The incident happened last Thursday around 9 a.m.

A few days later, police say officers caught up with the suspect.

Darius Whetstone, 27, was arrested Tuesday after police say he hit two more banks that morning. The first happened at the Bank of America in Oak Lawn at around 10 a.m.

An hour later, police believe Whetstone robbed a BB&T Bank five miles away along North Stemmons Freeway. Police say someone saw the suspect get into a white Toyota marked ‘for sale.’

Two Northwest Division patrol officers spotted it stuck in traffic and stopped the driver. According to police, he surrendered and is now in FBI custody.

Dallas police say the FBI is now handling the case.
