One of Eric Garner’s daughters marked Christmas Day by spreading personal information about an NYPD cop who was present during the chokehold death of her father — outraging officers still reeling from last weekend’s execution-style slayings of two policemen in Brooklyn.

Erica Garner tweeted that cop Justin D’Amico was “another officer that helped killed [sic] my dad,” and directed her 5,000-plus Twitter followers to a Web page that lists ­addresses for D’Amico and five possible relatives.

The information was viewed about 500 times before Garner’s stunning tweet was deleted following inquiries by The Post.

The move came less than a week after a gunman fatally shot cops Rafael Ramos and Wenjian Liu, following the shooter’s online post that said he planned to avenge the police killings of Eric Garner on Staten Island and Michael Brown in Ferguson, Mo.

It also came as cops were on high alert over dozens of copy-cat threats this week that have led to more than a half-dozen arrests.

An NYPD source said Erica Garner’s “disgusting” tweet “poses grave danger” to D’Amico.

“She clearly wants someone to go to the officer’s house and assassinate him in cold blood just like Ramos and Liu,” the source said.
