A concert in Rotterdam was canceled after Dutch police received a tip about a possible terror plot at the venue.
The American garage rock band Allah-Las was scheduled to perform on Wednesday night, but the event was called off after a warning from Spanish authorities led to the arrest of two men who officials suspected might be planning an attack, according to NPR's Soraya Sarhaddi Nelson.
As Soraya reported for NPR's Newscast unit:
"Dutch police say they contained the driver of a Spanish-registered van carrying some gas bottles near the venue where the Los Angeles band the Allah-Las was scheduled to play.
"Officials say it's unclear at this point whether the man, who says he is a mechanic and was intoxicated at the time of his arrest, was involved in any plot. Investigators say he had a logical explanation for why he had the gas bottles in his van. A search of his home turned up no evidence.
"Dutch broadcaster NOS reported police also arrested a second man, who is 22 [years old], at his home in the southern Netherlands in connection with the alleged plot."
There is no apparent connection between the warning and the terrorist attacks last week in Spain.
