Laravel Query Builder Where OR whereIn array - development

Laravel Query Builder Where OR whereIn array

I am having some trouble in Laravel using the query builder to select users based on two where clauses.
The first where clause would contain multiple where statements to select a user based on some conditions. If this fails in the OR part I would like to check simply if the user ID is in the array.
Would be grateful for some advice on how I could achieve this.
Thanks.

$rs = DB::table('tblUser')
        ->select('name')
        ->where(function($q) {
            $q->where(function($q){
              $q->where('fid', '=', $this->argument('fid'))
                ->where('type', '<', 10)
            })
            ->orWhereIn('id', $userIdSArray);
        })
        ->get();
