Law enforcement can arrest people or detain people.
You're subbing in "abduct" for one of those words.
If you don't have probable cause and you don't have a warrant, it's not an arrest and you aren't law enforcement. You're subbing in some words yourself.
abduct: to seize and take away (a person) by force
