A police operation saw armed officers deployed to an address in Selby yesterday (Sunday).
It followed a call saying someone was carrying a package which they believed contained weapons.
The police helicopter was also brought in as a back-up.
A North Yorkshire Police spokesperson said: “At around 5.22pm on Sunday, police received a call reporting that a man had been seen entering a property in Selby with a package that they believed contained firearms.
“Due to the information concerning firearms, which the police take very seriously, a large number of officers were deployed to the area including authorised firearms officers and support from the National Police Air Service.
“However, following a search of the property, no firearms were found and officers were satisfied that the incident was not as first reported.
“They did however, find suspected class A drugs and drugs paraphernalia that they seized from the property.”
Two men, aged 25 and 28, have been arrested on suspicion of drug dealing. The pair have been released “but remain under investigation while further enquiries are carried out”.
