Postal inspectors are distributing fliers to get the public's help in finding those who robbed a mail carrier of his all-important master key.

Postal officials on Friday distributed fliers seeking the public's help in solving the latest assault on a mail carrier by thieves seeking the master keys to mailboxes.

On Thursday afternoon, a veteran postal employee, with more than 20 years of service, was making his rounds in Pembroke Park when two men approached — and one of them hit him over the head with a blunt object, Inspector Ivan Ramirez said.

It was the second time in as many weeks that a mail carrier was robbed of valuable postal keys in Broward.

The latest attack happened at the Holly Tree Patio Villas, where postal inspectors returned Friday to circulate the fliers and speak with residents.

During Thursday's incident, the letter carrier fell to the ground and the attackers snatched master keys from his key chain and ran, Ramirez said. Generally, thieves use such master keys to open mailboxes, seeking checks, gift cards and personal information for identity theft, investigators said.

The mail carrier suffered a cut on his head that required stitches, he said.

"We're going to run through some [medical] procedures just to make sure there are no internal injuries," he said. "He was coherent, he was fine [and] he was able to provide a description and tell us what happened."

Because the blunt object wasn't left behind, "we don't know whether it was metal or whether it was wood," Ramirez said.

On April 14, an armed man stole master keys from a woman who was delivering mail in Lauderhill but she was unharmed, inspectors said. or 954-356-4303
