Temperatures were below freezing on Friday night.
Police initially tweeted that “a small number of monkeys may have fled the crash scene into the surrounding area,” following the accident that blocked traffic on SR 54 at I-80 near Danville.
It’s unclear how many monkeys were missing and if they were recaptured.

The Pennsylvania Game Commission is looking for the remaining monkey, according to PSP.
“We are asking that no one attempt to look for or capture the animal. Anyone who sees or locates the monkey is asked not to approach, attempt to catch, or come in contact with the monkey,” the PSP tweeted.
There were no immediate reports of injuries from the accident.
