Console logs- "mitmdump" ISSUE

Hello Team,
I am using mitmdump command to save logs.Command looks like -"/usr/bin/mitmdump -s -T &"
where “” is a python script to get human readable logs and log is saving to local drive.

Issue :- The command is running in background but logs are showing on terminal console. i don’t want this log to be shown on terminal. it should must be saved in a file rather than show on terminal.

OS : Ubuntu 16.04
