PHILADELPHIA — Cops in Olney and Logan were on high alert Thursday night after police say "credible threats" were made by gang thugs who said they were going to kill a police officer in retaliation for a fatal police-involved shooting earlier this week.
The message went out on police radio at 5 p.m. warning police to use extreme caution when responding to 2nd Street and Nedro Avenue — the scene of Sunday's shooting — and to Rockland between Broad and 13th.
