a question on completeness of a metrizable group

How to show that If G is a metrizable group. K is a closed normal subgroup of G, K and G/K are complete then G is complete.

( I have alreaady asked in math stacks but with no answer. I don't know if it is suitable for this forum.)

I don't think this is appropriate for MO. Can you link to your math.SE question? I will gladly give you hints there. – Steve D Jan 18 at 14:50

Please, next time wait at least a couple of days before reposting a question to another site. 9 hours is not nearly enough to conclude it will get no answer. – Emil Jeřábek Jan 18 at 15:00
