An unidentified Nigerian national was rescued by the Philippine Coast Guard after he jumped into the Pasig River wearing a pair of handcuffs of unknown provenance.

Village officials in Hulo in Mandaluyong City said they saw the man leap into the water at about 6 am, radio station DZMM reports.

The officials called the Coast Guard, who then fished him out of the river and noticed that he was wearing handcuffs.

The Nigerian man told the Coast Guard that before jumping into the river, he had visited a Makati police station but did not explain why.

He also didn’t say how he ended up in Mandaluyong, according to radio station DZBB.

He was taken by the Coast Guard to a Mandaluyong City police station where they determined that the handcuffs he was wearing did not belong to the Philippine National Police, Remate reports.

The man remains at the police station, where he is currently being questioned by the authorities.
