The sister of ex-NBA star Sebastian Telfair has been arrested again — this time for allegedly violating a restraining order three times in February, cops said Tuesday.

Octavia Telfair, who turned 33 Tuesday, is accused of banging and kicking on the front door of a 44-year-old man’s Flatbush apartment at around 10 p.m. on Feb. 14 and just after midnight on Feb. 24, according to the NYPD. Octavia also allegedly texted and called the man, cops said.

Octavia was arrested just after 9 a.m. Tuesday on three counts of criminal contempt for allegedly violating her protective order, according to the NYPD.

This is the second time in as many days the Coney Island woman was picked up by authorities.

On Monday, the FBI nabbed her for allegedly threatening her brother’s ex-wife across state lines. The ex, Samantha Telfair, had previously testified that she has seen the former Portland Trailblazer with guns.

Octavia Telfair has been arrested nine other times since 2006, sources told The Post.
