Question Delete rows with unique value for specific column

Hi all
I have a file which looks like this
Code:
1234|1|Jon|some text|some text
1234|2|Jon|some text|some text
3453|5|Jon|some text|some text
6533|2|Kate|some text|some text
4567|3|Chris|some text|some text
4567|4|Maggie|some text|some text
8764|6|Maggie|some text|some text

My third column is my KEY and I want to only print lines of the file if the KEY has been printed more than once. So basically any unique entry for column three can be deleted.
Code:
So the output would look like this
1234|1|Jon|some text|some text
1234|2|Jon|some text|some text
3453|5|Jon|some text|some text
4567|4|Maggie|some text|some text
8764|6|Maggie|some text|some text

Can you please help me?
