Transportation Security Administration (TSA) officers at Indianapolis International Airport discovered two smoke grenades concealed inside a jar of peanut butter in a passenger’s checked luggage on December 21, 2023. The discovery led to the temporary closure of a baggage screening area, though airport operations remained largely unaffected by the incident.
How the discovery occurred
TSA officials identified the suspicious items during routine checked baggage screening. According to a statement from the TSA, officers observed an anomaly on the X-ray monitor that prompted a physical inspection of the passenger’s luggage. Upon opening the jar of peanut butter, security personnel found the smoke grenades embedded within the substance.

The agency noted that the passenger was traveling through the airport when the items were flagged. Following the discovery, law enforcement officers were notified to manage the scene, as explosive or incendiary materials are strictly prohibited in both carry-on and checked baggage.
Why smoke grenades are prohibited
Smoke grenades are classified as incendiary devices. Under federal regulations enforced by the TSA, these items are banned from all aircraft because they pose a significant fire and safety risk.
While some passengers may attempt to conceal prohibited items to bypass security protocols, the TSA utilizes advanced imaging technology and physical searches to detect non-metallic and obscured threats. The agency’s Prohibited Items list explicitly bars any form of explosive or incendiary device, regardless of the concealment method used.
What happens to passengers who violate TSA rules
Passengers found with prohibited items in their luggage may face several consequences, depending on the nature of the object and the intent behind its transport. According to the TSA, violations can result in:
- Civil Penalties: The agency can issue fines reaching several thousand dollars for security violations.
- Criminal Referral: Local law enforcement may choose to detain or arrest individuals if the items violate state or federal criminal statutes.
- Loss of PreCheck: Travelers enrolled in the TSA PreCheck program may have their eligibility revoked.
