Grabing and droping

Hello, i'm working on a top down game, and i want the character to be able to grab and drop objects, like a box or crate.
The player aproachs the crate, presses a button and then the object gets attached to the player, then the player may press the button again to drop the object.
I need help with that.

There is no grid, the player moves freely and should be able to grab the object from all the sides.
I guess i should be attaching the rigidbody somehow to follow the player.
