how to validate checkbox with multiple names in checkbox (BOOTSTRAP VALIDATOR USED)

Question

Hi there here is the html code, as you can see it has different names in the input, i wanted to validate this bootstrap js so that atleast one checkbox has to be selected before the form submission. Below will be the javascript I have used for radio buttons since they have same name. Thank you `

<div class="form-group required">
                    <label class="col-md-2 control-label" required>Q2. Which event did you attend?</label>
                    <div class="col-md-4">
                        <div class="checkbox">
                            <label>
                                <input class="validateCheck" type="checkbox" name="Event_Mel" value="true" />Melbourne</label>

$(document).ready(function() {
$('#contact_form')
    .on('init.field.fv', function(e, data) {
        // data.field   --> The field name
        // data.element --> The field element
        if (data.field === 'checkEvents') {
            var $parent = data.element.parents('.form-group'),
                $icon   = data.element.data('fv.icon');
            $icon.appendTo('#feedbackIcon');  // <--- Move the icon to this element
        }
    })
    .formValidation({
        framework: 'bootstrap',
        icon: {
            valid: 'glyphicon glyphicon-ok',
            invalid: 'glyphicon glyphicon-remove',
            validating: 'glyphicon glyphicon-refresh'
        },
        fields: {
            validateCheck: {
                selector: '.validateCheck',
                err: '#message',      // <---- All messages of checkEvents will be placed inside this element
                validators: {
                    notEmpty: {
                        message: 'Please choose at least one checkbox'
