Don't use the "on."

Don't use the "on."

I found a statement in EnglishForums as following

You use 'on' with the noun investigation rather than the verb.
I will investigate on this problem. incorrect.
There will be an investigation on this problem. correct.

Is this an correct statement?

"There will be an investigation into this problem" is better than "...on this problem."
