Bash script if statement followed by multiple OR's

I have the problem that I want an if statement that makes sure the first statement is true and one or more of the following three statement are also true in a bash script.

The code I currently have is:

if [[ $TAIL != "true" ]] && [[ -f $FILE_DIR/.completed ]] || [[ -f $FILE_DIR/../.completed ]] || [[ -f $FILE_DIR/../../.completed ]]

I have also tried: 

if [[ $TAIL != "true" ]] && [[ [[ -f $FILE_DIR/.completed ]] || [[ -f $FILE_DIR/../.completed ]] || [[ -f $FILE_DIR/../../.completed ]] ]]

but neither work.

Anyone any ideas on how to fix this?

Thanks in advance for help.

The answer is as shown below:

if [[ $TAIL != "true" ]] && ( [[ -f $FILE_DIR/.completed ]] || [[ -f $FILE_DIR/../.completed ]] || [[ -f $FILE_DIR/../../.completed ]] )

You can do it all inside one [[]]:

if [[ $TAIL != "true" && ( -f $FILE_DIR/.completed || -f $FILE_DIR/../.completed || -f $FILE_DIR/../../.completed ) ]]

you can group your OR statements with parentheses:

if [[ $TAIL != "true" ]] && ( [[ -f $FILE_DIR/.completed ]] || [[ -f $FILE_DIR/../.completed ]] || [[ -f $FILE_DIR/../../.completed ]] )
