Jersey City Mayor Steven Fulop doubled down Wednesday morning on his assertion that the gunmen who sparked a deadly firefight in the city had targeted a Jewish grocery store — and said that surveillance footage proves it.

“Last night after extensive review of our CCTV system it has now become clear from the cameras that these two individuals targeted the Kosher grocery location on MLK Dr,” Fulop tweeted around 6:30 a.m. “The 2 JCPD officers that were on a foot post one block away immediately responded/engaged and prevented the perpetrators from leaving that location and harming any further civilians.”

Fulop initially stated Tuesday night that the store was targeted, based on an “initial investigation” but did not elaborate. His tweets on Wednesday also didn’t clarify whether the attack was believed to be anti-Semitic or otherwise.

Detective Joseph Seals was killed in the gun battle that kicked off at about 12:30 p.m. in the Greenville neighborhood when police responded to a report of gunfire near the supermarket.

In addition to Seals, three civilians inside the store and both suspects were killed in the shootout.

In his Wednesday tweet, the mayor added that there are “no credible further threats from this incident” but local patrols have been increased as a result.

The state Attorney General’s office, as well as the Hudson County Prosecutor’s Office, will be handling the investigation, he confirmed.
