The Royal Gibraltar Police are investigating the causes of a strange accident involving a Spanish Civil Guard patrol boat in waters surrounding the Rock's port, specifically 'in front of the western side of the airport runway,' as indicated by the RGP in a tweet.

Based on this information, and pending official information from the Spanish side, as shown in images circulated on social media around 10:15 p.m., the Civil Guard patrol boat collided with the runway approach lights at the western end of the airport runway. Some witnesses even reported to the Gibraltar police that the Spanish vessel was sinking.

According to reports received by the RGP, the collision occurred moments after the Civil Guard boat chased rigid-hulled inflatable boats (known as 'narco boats') that had fled the area.

Reports also suggested that before the collision, sounds 'similar to gunfire in the sea' were heard, as stated in the RGP communication.

Gibraltar authorities dispatched personnel to the scene, but the involved patrol boat left the area heading towards Spain.

The Port Captain and the Police Commissioner reportedly contacted their respective counterparts regarding the incident.

There is no official information on possible injuries on the Spanish boat, although investigations are ongoing.
