One Sunday afternoon, while standing at the corner of C.P. Garcia and Katipunan Avenues, an off-duty police officer accosted a motorcycle rider and asked them to alight. The off-duty police officer then inspected the motorcycle's compartment box. Pretending that a sachet of shabu was found, the off-duty police officer demanded PHP1,000.00 in order to prevent an arrest.

Fearful of being incarcerated for life for a crime that was not really committed, the motorcycle rider readily complied. Unknown to the off-duty police officer, a surveillance camera caught the entire incident. Will a charge of robbery prosper against the off-duty police officer? Explain briefly. (2020-21 BAR)
