But he’s been arrested.”<br /><br />The staff member said the front door to the property was usually left unlocked as there was no other way out of the address in case of a fire.<br /><br />She added: “We’ve just been told that the door was open downstairs but it’s always open because there’s no alternative exit from that room. There’s no fire door. <br /><br />“Also we have to keep it open as the children want to go to the toilet constantly and it's just outside the door – the toilets. <br /><br />“It’s a lock with a key – you’d have to keep all the kids locked in with a key.”<br /><br />“The Hart Space is the most lovely, lovely relaxing place. Usually, it's for babies.<br /><br />"It’s a holistic kind of thing – for yoga and all that type of thing. For babies and pregnant women.”<br /><br />Emergency services flooded the area after being called at around 11.50am today (Mon).<br /><br />Armed officers, 13 ambulances and four air ambulances were dispatched to the scene and a huge police cardon has been put in place.<br /><br />Photos from social media show the major response, which one local said included 'around 20 police cars at the scene'.<br /><br />Merseyside Police have not confirmed how many casualties have been injured, but urged the public to avoid the area near Hart Street in the town.
