Nexus 4 will not turn off

Just charged my Nexus 4 and tried to take some pictures.....would not work.....kept saying no connection.....it then started reopening the facepage very quickly and would not stop.....tried to turn it off but it will not shut down and will not unlock so I cannot open it on my computer to try to save my information in case it goes to sleep permanently......heeelllp!!!
