MIAMI – Police are investigating a series of early morning robberies in Miami.

Miami police Officer Michael Vega said at least seven people were robbed by a group of men who asked the victims, "What time is it?" before pulling out a gun.

The group of men demanded cash and belongings from the victims.

One of the victims was the owner of Ela's Bakery Cafe in Little Havana.

"Once the victim realized that they had a firearm and that they were robbing him, he complied and he gave them his wallet," Vega said.

Then the robbers demanded the bakery owner's keys. He wouldn't give them up.

Vega said the owner was armed and fired his gun at the thieves as they were getting away.

Elas Knight, who works at a food market next to the bakery, said someone came in and tried to steal her tip jar, but she snatched it away.

Blocks away, a man was reportedly riding his bike when he was cut off, pistol whipped and robbed of his backpack.

Vega said the crime spree stretches from Little Havana to Coral Way.

Authorities believe four people are involved in the robberies. Anyone with further information is asked to call the Miami Police Department or Miami-Dade Crime Stoppers at 305-471-8477.
