Bill Bratton is tweeting up a storm

The NYPD can’t seem to meet its Twitter quota — but the city’s top cop is one of social media’s finest.

Police Commissioner Bill Bratton is tapping into the self-promoting spirit of Twitter by posting dozens of photos of himself — posing with cute kids, riding the Staten Island Ferry and wearing a fancy white bowtie.

Weeks after an NYPD mandate directing precincts to post a minimum of four tweets a day, only six precincts of the city’s 76 are meeting the quota, according to week-long sample of data reviewed by The Post.

Many precincts have failed to set up a Twitter account whatsoever. Others tweet only a few times a week or take the easy way out by re-tweeting other users’ original ideas.

Bratton, on the other hand, has no trouble churning out lively, original, 140-character-maximum content on Twitter — including shots of his red-and-white birthday cake, images of himself marching in a parade and standing next to a brave police dog.

“An excellent day marching with the @NYPD_Columbia Assoc. & #NYPD Band in the annual Columbus Day Parade,” he tweeted on Oct. 13 along with the photo.

“A beautiful ride on the Staten Island Ferry this morning,” he proclaimed on Oct. 10.

He is also featured in a photo wearing a white bowtie and tux at a charity dinner at the Waldorf Astoria.

Of the precincts with active Twitter accounts, the biggest slackers were the 106th Precinct in Jamaica, Queens, which tweeted just three times in the one-week period — far less than the quota of 28 tweets per week.

Other precincts, including the 76th Precinct in Carroll Gardens, Brooklyn, and the 6th Precinct in the West Village, have yet to even set up a Twitter account.

The laziest precinct was the 67th, which relied entirely on re-tweeting and didn’t post a single original tweet during the week-long period.

The most active precinct was the 110th Precinct in Elmhurst, Queens, which tweeted 80 times in one week. The precinct has earned 1,178 followers.

In September, precinct commanders were required to attend a seminar about how to use social media after some initial blunders.

The NYPD later sent out a memo with tips about how to gain followers and connect with the community by tweeting frequently and “using humor.”

Several precincts have had accounts set up but have yet to post a single tweet.

The Post reviewed Twitter data from the week of Oct. 8-14.
