From article:

Four people were injured in the brutal attack Thursday evening at Nazareth Restaurant and Deli, a Mediterranean restaurant in Columbus. The victims were taken to an area hospital and were expected to recover.

Police identified the suspected attacker as Mohamed Barry, 30.

CBS News homeland security correspondent Jeff Pegues reports that investigators were running down leads to try to determine if the attack was somehow tied to terrorist organizations.

"There was no rhyme or reason as to who he was going after," said Columbus police Sgt. Rich Weiner.
Police said the man walked into the restaurant, had a conversation with an employee and then left. He returned about a half hour later. That's when police said he approached a man and a woman who were sitting just inside the door at a booth and started the attack.

Pegues reports the suspected attacker has a Somali background, and officials believe he may have traveled to Dubai in the United Arab Emirates in 2012. Pegues reports that law enforcement is concerned that this incident has the hallmarks of the type of so-called "lone wolf" terrorist attack that they have been working to stop.
