Federal officers seized drugs worth about $290,000 in two separate incidents recently at the port of Nogales.

Both incidents occurred Thursday at the Mariposa crossing, said U.S. Customs and Border Protection officials in a news release.

In the first incident, a 54-year-old man from Mexico was pulled over for a further inspection of his tractor-trailer. A drug-sniffing dog alerted to possible drugs in the engine's valve cover.

Officers found six packages of heroin weighing more than 16 pounds and valued at about $225,000, states the news release.

In the second incident, a 30-year-old man from Mexico was pulled over for a second inspection of his Toyota sedan. Officers found 10 packages of methamphetamine weighing more than 21 pounds. The drugs were worth about $65,000.

The men were turned over to federal officials, and the vehicles and drugs were seized.
