WEST CHESTER, Ohio (The Blaze/AP) — Briefcases with handwritten signs attached were left at the front door of U.S. House Speaker John Boehner’s Ohio office, bringing out a bomb squad.

Investigators in the Cincinnati suburb of West Chester tell multiple media outlets that the bomb squad blew the cases apart on Sunday and found they contained only papers. No one was hurt.

WCPO-TV captured the bomb squad robot removing the briefcases and exploding them:

WCPO reports the signs were on colored paper and included messages with the words “jobs,” “oil” and “gas.” A West Chester officer on patrol first noticed the briefcases outside the Republican congressman’s office late Sunday morning.

Boehner spokeswoman Brittany Bramell said that investigators’ “vigilance and efforts” were appreciated.
