General arrest:
* പിടികൂടൽ (pidikoodal) - This literally means "seizing" and is the most common translation for "arrest."
* തടവിലാക്കൽ (thadavilakkal) - This means "detaining" and implies a more formal process of taking someone into custody.
Other specific contexts:
* നിർത്തുക (nirthuka) - This means "to stop" and can be used to describe the arrest of a process or activity.
* സ്തംഭിപ്പിക്കുക (sthambyppikkuka) - This means "to freeze" or "to paralyze" and can be used to describe the arrest of a physical movement.
Ultimately, the most accurate Malayalam translation of "arrest" will depend on the specific context in which it is used.
