CLEVELAND HEIGHTS, Ohio -- Cleveland Heights police say they have five individuals in custody who either have information or are believed to be involved in the shooting death of restaurant owner, Jim Brennan.

The suspects are all from Cleveland and range in age from 20-23 years old. Police are not releasing their names at this time.

Some of the suspects were arrested Monday, some Tuesday and some Wednesday.

Police are looking into the possibility it could be gang-related.

At a press conference Wednesday evening, Cleveland Heights Police Chief Jeffrey Robertson said, "I want it understood that there is a lot of talk and speculation going on that these cowards-- I call them cowards-- because that is what they are; individuals who preyed upon an innocent business owner-- a district in this city that's a special district in this city, as they all are; one that thousands of people have been to in their lives. Thousands of people knew Jim Brennan and as you can see by the investigation, we are going to do it to the fullest."

Police say two people broke into Brennan's Colony on Lee Rd. on Monday. Brennan, 61, was shot after what authorities say was a struggle. He later died at the hospital.
