spherically symmetric stars with uniform energy density profile a variety of special solutions having asymptotically Schwarzschildian character and satisfying the braneworld boundary conditions were found [@Ger-Maar:2001:]. The most popular is the one with external spacetime described by the Reissner-Nordström geometry with the braneworld tidal charge parameter reflecting the tidal effects of the bulk and related to the energy density and brane tension. Its properties were extensively studied both in the weak field limit [@Boh-Har-Lob:2008:CLAQG:; @Boh-Ris-Har-Lob:2010:CLASQG] and strong field limit when some restrictions on the brane tension were implied from the data of kHz QPOs observed in low mass binary systems with a neutron star [@Kot-Stu-Tor:2008:CLASQG:]. Here we focus our attention to the interior of the compact objects, namely to the phenomena related to trapping of neutrinos in the so called Extremely Compact Stars (ECS) admitting (by definition) existence of trapped null geodesics [@Stu-Tor-Hle-Urb:2009:]. Usually, the braneworld tension is assumed positive while the related tidal charge has to be negative [@Ger-Maar:2001:], but the negative tension and related positive tidal charge are not excluded [@Dad-Maar-Pap-Rez:2000:PHYSR4:], so we consider here both positive and negative tidal charge of the compact object. Note that exterior of neutron stars with positive tidal charges can be described
