False alarm

So, Spain open as usual after easter. Arrived at guitar class to find Jordi trying to switch the building's alarm system off...which turns out to be impossible. Sit down to start class and his mobile phone rings. Head of music school ringing to find out if the alarm is still ringing. Mobile phone gets cut off. Mobile phone rings again. Head of school ringing back to see if alarm is still ringing (it is). Class starts again. Door bursts open and two six foot eight uniformed policemen barge in.
"Sorry," says Jordi, "can't turn the fooking alarm off."
"Fook," say the policemen.
"Do you know how to turn it off?" asks Jordi.
"Fooked if we know," the policemen answer. "No trouble here then?"
"No," Jordi replies.
"Oh hey," The taller of the two tall policemen says as he peers at the music stand..."Astor Piazzolla...Ausencias...Isn't Piazzolla fantastic!"
"Yes," Jordi agrees..."Erm...the alarm?"
"Sorry," the policemen burble into their radios as they leave. "Shall we shut the door to the street as we leave?"
