CLEVELAND, Ohio – An armed robber took U.S. and Palestinian passports and other valuables after he lured a man and woman to Cleveland under the guise of selling them a cellphone through the online marketplace OfferUp, police reports say.

The unidentified robber also took two cellphones, a Social Security card, a TAG Heuer Carrera watch, a purse, a wallet and cash from the man and woman during the Sunday incident on East 136th Street near Harvard Avenue, according to a police report.

No arrests have been made in the case, which remains under investigation, police said.

The unidentified robber stole the items at gunpoint from a 27-year-old man, who is identified in a police report as a tourist, and a 22-year-old woman. The pair, who are listed in the report as having the same Strongsville address, did not return a phone message seeking comment about the robbery.

The man and woman arranged to buy an Apple iPhone XS Max listed for sale on OfferUp. They drove to Cleveland and met the seller about 7 p.m. Sunday.

The robber got into the back seat of their car and handed the cellphone to the man and woman. They were checking it out when the robber pulled out a gun and demanded everything they had, police reports say.

The robber got out of the car and ran away after he took their property. The man and woman then drove to the Cleveland police department’s Fourth District station to report the robbery.

The man and woman told investigators the robber still had other posts listing items for sale through OfferUp, police reports say.

Robberies involving people who are trying to buy or sell items through online marketplaces such as OfferUp and Craigslist have become more common in recent years. Their frequency has caused some area police departments to designate their stations as “transaction safe zones” where buyers can arrange to meet sellers.

A Cleveland police spokeswoman said earlier this year that the department has not designated any specific “safe zones” to meet an online buyer or seller, but police recommended meeting in safe, well-lit locations.
