OAKLAND -- A man who just robbed a Temescal district bank Thursday afternoon was splattered in red ink and dropped the loot when a dye pack included in the wad of bills exploded, police said.

The robbery happened about 12:25 p.m. Thursday at the Bank of the West, 4900 Telegraph Ave.

Police said the man gave a teller a note demanding cash. The note also said the man had a gun although none was seen.

The man fled with an undisclosed amount of greenbacks.

But just after exiting the bank a dye pack included with the money exploded, dousing the man and some of the bills with red ink, witnesses told police. The man dropped the money and fled. The money was recovered by police.

He was wearing a light gray hooded sweatshirt, white T-shirt and white sweatpants that are now covered with red ink.
