STOCKHOLM, Feb 7 (Reuters) - Securitas, the world's second-biggest listed security services group, reported on Wednesday a rise in core profit that slightly lagged expectation, and said profitability was dragged down with poor results in its Critical infrastructure services.
Operating profit before amortisation (EBITA) at the Swedish company rose to 2.68 billion Swedish crowns ($255.70 million)from a year-ago 2.49 billion.
This was against an average analyst forecast of 2.75 billion in a poll provided by the company.
