Holding my hand with both his hands what does this indicates?

This is a colleague of mine, we work together but he works remotely as he lives in another city.

We met for second time in person at an office party, he texted me to go where he was to see me.

While chatting he smiled a lot and suddenly he took my hand and placed both his hands below and on top of my hand, like giving me a hug with his hands, while looking into my eyes prolonged eye contact. This lasted for more than 2 - 3 minutes or so.

After that we had to say goodbye because he had to go and speak to some other colleagues. Does this mean something?

He said to me that he likes my personality and that I have gained his interest, also that I m the best person he's ever met.. . Does this imply romantic interest or is it pure friendly? Please advise!
