MIAMI (CBSMiami) – U.S. Postal Inspectors released a sketch Wednesday of a man wanted in connection with the attack on a mail carrier last week in Pembroke Park.

“If somebody knows this person, they know them,” Postal Inspector Bladismir Rojo told CBS4 News.

The sketch shows a man appearing to be in his 20s wearing a hooded sweatshirt.

He’s one of two attackers who hit a postal worker in the head last Thursday and stole his keys as he was delivering mail to the Holly Tree Patio Villas on SW 52nd Avenue.

The Post Office is offering up to a $10,000 reward for information leading to an arrest.

Residents in the area, many who want him caught, said the attacker doesn’t look familiar.

“I hope they keep him in jail for a long time,” said Victor Beteta whose wife saw the attackers flee in an older model light colored van.

Beteta said his wife was handing the carrier a letter that ended up with blood on the envelope.

The carrier needed stitches and has not returned to his route.

Resident Pierre Mexima said he gets a lot of credit card applications and he’s been checking to make sure none of his personal information has been compromised.

“It’s very concerning you have stuff coming in all the time.”

Agents also want to catch the man who robbed a female carrier of her keys in Lauderhill several weeks ago.

That assailant was wearing orange sneakers.

At this point, inspectors don’t know if the two crimes are connected.
