The man who cops think is tied to the slaying of Yoseph Robinson tried to make a run for it when he was briefly left alone and unhandcuffed in an interrogation room at the 70th Precinct stationhouse.

Cops quickly corralled the possible suspect, and the man, who has not been charged in Robinson’s murder, busted his head in the scuffle.

Police had received several tips that the man held up the MB Vineyards liquor store in Midwood last Thursday and then shot Robinson, who was trying to defend his girlfriend.

Investigators unearthed a license plate for the possible suspect’s car, the sources said. Detectives tracked it down, watched it until the owner arrived before dawn and took him into custody.

The man has not confessed and investigators do not have enough evidence to charge him, the sources said.

He was wanted on an unrelated assault warrant and is expected to face charges in that case.

The robber who held up the liquor store was wearing a mask, making it more difficult to positively identify him, the sources said.

The gunman pointed his revolver at the head of Lahavah Wallace, Robinson’s girlfriend. That prompted the clerk to desperately reach for the weapon – only to be fatally shot himself.

The Jamaican-born Robinson left a hip-hop career and turned away from a troubled past to convert to Judaism.
