To Capture, To Apprehend
する verb
たいほする
もし今この場を去らなければ、公務執行妨害で逮捕するぞ。
If you don’t leave now, I’ll arrest you for violating laws against interfering with a public servant in the line of duty.
Remember how 逮捕 is an "arrest" or "capture"? This is the verb version, and it is to arrest or to capture.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well. Will also be helpful to know the word 逮捕 already as well.
