The ESB has described a stunt where three skydivers flew between the Poolbeg Chimneys in Dublin as a "serious safety incident".
Footage shows Red Bull's Marco Fürst, Marco Waltenspiel and Max Manow flying through the two chimneys this morning, reaching a top speed of 253km/h and completing their flight in just over a minute.
The ESB says it was not approached in relation to the skydive and did not give permission for it to take place.
Red Bull Ireland has said the stunt was carried out "with rigorous safety measures and with the permission from all the required relevant authorities".
