India, March 18 -- Joshua Riibe, the person of interest in the disappearance of University of Pittsburgh student Sudiksha Konanki, has given Dominican Republic cops an ultimatum. His attorney Beatriz Santana said in a motion filed Monday, March 17, that Riibe cannot be detained any longer without being charged, and must be allowed to go home.

Riibe has not been charged or accused of wrongdoing, but is being considered a person of interest. Authorities in the Dominican Republic have seized his passport, and the Dominican government also said that he has also been put under police monitoring. He was interrogated by Dominican Attorney General Yeni Berenice Reynoso and Navy Vice Admiral Agustin Morillo Rodriguez.
