Unknown tag above my header

Hi, since a while I have an unknown tag above the header of my website. Do you know what this is and how I can remove it? (http://prntscr.com/lnaps7)

Hello there,

It looks like it’s Google Analytics tracking script.

Theme doesn’t have such this script by default. Please check your plugins if there’s one used to insert it.
