Can not find an a link to delete it   

I can not find the foreign key object to delete it, it says:

"This relationship is not shown because the entities it is connected to are
not placed on the diagram."

How can I delete it, please help.

P.S.:

it is for database modelling & I am using the Enterprise Architect version
