BOSTON -- The international manhunt for a father accused of kidnapping his 7-year-old daughter in Boston has ended. Clark Rockefeller, who had been on the run from authorities for six days, is in custody in Baltimore, according to officials.

Sources have confirmed that his daughter, Reigh Boss, was also located in the Baltimore area and is in good condition. It is unclear whether she was found with her father.

The conditions of Clark Rockefeller’s arrest are still unknown at this time. The 48-year-old was picked up late Saturday afternoon at an apartment in the Mount Vernon neighborhood north of downtown, according to Baltimore Police spokesman Sterling Clifford. He was taken into custody by FBI agents and Baltimore police.

Boston police have refused to comment on the investigation until a scheduled press conference at 6 p.m.

Rockefeller and his daughter were last seen at Grand Central Terminal in New York earlier in the week. Since then, Boston police have received hundreds of tips from across the country about the pair’s whereabouts. Some of the reported sightings include: Port Jefferson, N.Y.; Smyrna, Del.; and Turks and Caicos.

Turks and Caicos Detective Sgt. Calvin Chase said Friday that Rockefeller was spotted on two occasions and that the girl's hair had been cut short. He said Rockefeller was spotted at 9:30 a.m. at a NAPA auto store and then at 2:30 p.m. at a 7-Eleven convenience store.

Boston police said Friday that the girl and man were not the Rockefellers, but officials did not disclose how they ruled out the sightings.

On Thursday, Reigh's mother, Sandra Boss, made a plea, asking her former husband to bring her "princess" home safe.

"Although many things have changed, you will always be Reigh's father and I will always be Reigh’s mother. We both love her dearly and have only her best interests and well-being in our hearts. I ask you now, please, please bring 'Snooks' back. There has to be a better way for us to solve our differences than this way," Boss said. "And Reigh, honey, I love you and miss you so much. Remember you're always a princess."
