This is somehow unique. A twitter user account compromised and used to make demands for hacked users web based systems. The most common bitcoin related demands I have come across so are Ransomware infections on PCs/Laptops. 

The tone of the demand from the the tweets point to the hack being done locally, this is in reference to "UPDATE" and "Breaking News". I would not be surprised if it was an inside job.

Someone has hacked the twitter handle for UoN https://twitter.com/ict_uonbi, and taken control of it. He has asked for 10BTC and posted the account where the BTC should be sent to.

The exchange rate is 1 bitcoin is USD 650 https://www.google.com/?gws_rd=ssl#q=10btc+to+%24

Then to demonstrate that this is not a joke,  the person(s) have started posting passwords for different systems and Emails accounts for UoN.

Not sure though if these are the real passwords or its just empty threats. 

It would be interesting to hear from experts.
