How to Remove LinkedIn Insight Tag from my website

I can see the following LinkedIn Insight code when I view the source code of any pages. But I am not able to find that from where it has been added.

I have already checked Settings > Advanced > Code Injection > Footer. But it's not there. Can anyone please help from where I can remove it?

Here is the code:

<script type="text/javascript">
_linkedin_partner_id = "2785588";
window._linkedin_data_partner_ids = window._linkedin_data_partner_ids || [];
window._linkedin_data_partner_ids.push(_linkedin_partner_id);
</script><script type="text/javascript">
(function(){var s = document.getElementsByTagName("script")[0];
var b = document.createElement("script");
b.type = "text/javascript";b.async = true;
b.src = "https://snap.licdn.com/li.lms-analytics/insight.min.js";
s.parentNode.insertBefore(b, s);})();
</script>

<img height="1" width="1" style="display:none;" alt="" src="https://px.ads.linkedin.com/collect/?pid=2785588&fmt=gif" />
