け as a contraction of 来い


I’d like to confirm my theory that 来い at the end of a sentence can be
colloquially contracted to け. I met this sentence in a comics:

> 置いてけ。

A meaning “Leave it here!” would be very appropriate there. So I suggest that
the copula at the end is an imperative こい as mentioned
[here](https://japanese.stackexchange.com/questions/63131/meaning-
of-%E3%81%97%E3%81%A3%E3%81%8B%E3%82%8A%E9%A0%91%E5%BC%B5%E3%81%A3%E3%81%A6%E3%81%93%E3%81%84/63192#63192).

Am I right? Thanks!
