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.

The head of the NYPD sergeants union, Ed Mullins, called the tweet “terrible behavior that continues to cause divisive actions throughout the city.”

“The apple doesn’t fall far from the tree,” Mullins added.

D’Amico got immunity to testify before the Staten Island grand jury that earlier this month cleared fellow cop Daniel Pantaleo in Eric Garner’s July 17 death while he was being arrested for illegally peddling loose cigarettes.

The grand-jury ruling sparked an ongoing wave of anti-cop protests that have been roiling the city, with agitators chanting for the deaths of cops and attacking two NYPD lieutenants on the Brooklyn Bridge.

In her 1:45 a.m. tweet, Erica Garner posted a link to a page on the pastebin.com Web site, which lets users anonymously post plain-text documents for public viewing.

She called the information about D’Amico “just something light” and included the hashtag #Doxx, which refers to the online practice of revealing private details about people’s lives.

Garner family lawyer Jonathan Moore, who is preparing a $75 million suit against the city, didn’t deny that Erica Garner posted the tweet, but maintained that she “did not have any knowledge of what was in those links.”

“Nobody in the Garner family, including Erica, would consciously send information out about the personal address or phone number or any identifying information about the police officers, particularly after what happened to those two officers,” Moore said.
