You terminate a session by killing its parent process, called the session leader. Find out which process it is with:
ps -dN|grep pts/3
To kill and logout a user, you can send KILL signal. Type the following command:
# skill -KILL -u vivek

Improving a bit Fabel's answer above:
\# *for pid in $(for ptsn in $(w | grep **user_name** | grep pts | awk '{print $2}'); do ps -dN | grep "$ptsn " | awk '{print $1}' ; done); do kill -9 $pid; done*
